Colour Grading Fundamentals
Knowledge check
Q1. What is the primary purpose of colour grading in film production?
- A. To capture the original footage on set
- B. To adjust and enhance the colour and tone of footage to achieve a desired look and mood ✓
- C. To edit the sequence of shots into a final narrative
- D. To add sound effects and music to a scene
Why: Colour grading shapes the visual tone, mood, and consistency of footage after it has been shot, helping to convey emotion and style.
Q2. Which term describes the overall brightness or darkness of an image?
- A. Saturation
- B. Hue
- C. Luminance ✓
- D. Contrast ratio
Why: Luminance refers to the brightness level of an image, while saturation relates to colour intensity and hue refers to the colour itself.
Q3. What does saturation control in an image?
- A. The lightest and darkest points of the image
- B. The intensity or vividness of colours ✓
- C. The position of colours on the colour wheel
- D. The sharpness of edges in the frame
Why: Saturation determines how vivid or muted colours appear, from fully intense to greyscale.
Q4. What is the purpose of a LUT (Look-Up Table) in colour grading?
- A. To store audio levels for mixing
- B. To map input colour values to new output values, applying a consistent colour transformation ✓
- C. To organise clips in the editing timeline
- D. To measure the frame rate of footage
Why: A LUT is a table that transforms colour values from one space or look to another, allowing quick and consistent application of a grade.
Q5. Which colour grading approach involves correcting technical issues like white balance and exposure before creative styling?
- A. Creative grading
- B. Primary correction ✓
- C. Secondary correction
- D. Vignetting
Why: Primary correction adjusts the whole image's exposure, white balance, and contrast to produce a neutral, accurate base before creative work begins.
Module 2
Module 2: Understanding Colour Spaces and LUTs
Understanding Colour Spaces and LUTs
Knowledge check
Q1. What is the primary purpose of a color space in film production?
- A. To determine the resolution of the final video file
- B. To define the range and relationships of colors that can be captured, processed, and displayed ✓
- C. To compress the video so it takes up less storage space
- D. To set the frame rate at which footage is played back
Why: A color space defines the range of colors (gamut) and how those colors are represented numerically, so that capture, processing, and display all interpret color consistently.
Q2. What does LUT stand for in color grading?
- A. Light Unit Transfer
- B. Linear Utility Texture
- C. Look-Up Table ✓
- D. Layered Universal Track
Why: LUT stands for Look-Up Table. It is a set of instructions that maps input color values to output color values, allowing a consistent transformation to be applied to footage.
Q3. Which type of LUT is typically used to convert log-encoded footage into a viewable image for monitoring on set?
- A. A creative LUT
- B. A technical or display LUT ✓
- C. A black and white LUT
- D. A sharpening LUT
Why: Technical (or display) LUTs convert flat, log-encoded footage into a standard viewable image so the crew can judge exposure and framing. Creative LUTs are applied later to establish a stylistic look.
Q4. What is the main difference between a 1D LUT and a 3D LUT?
- A. A 1D LUT works on each color channel independently, while a 3D LUT considers how red, green, and blue values interact ✓
- B. A 1D LUT is only used for black and white footage
- C. A 3D LUT can only be applied to audio files
- D. A 1D LUT has more color information than a 3D LUT
Why: A 1D LUT transforms each channel separately, which is limited for complex color shifts. A 3D LUT maps combinations of red, green, and blue together, allowing far more nuanced and accurate color transformations.
Q5. Why is it important to know the color space of your footage before grading?
- A. It determines the file name of the exported video
- B. It ensures you apply the correct transforms so colors render accurately and consistently ✓
- C. It changes the audio sync of the project
- D. It automatically adds visual effects to the shot
Why: Knowing the source color space lets you apply the correct input transform or LUT, so the image is interpreted properly and grading decisions are made on accurate color rather than distorted values.

Module 3: Primary Correction Techniques
Primary Correction Techniques
Knowledge check
Q1. What is the primary purpose of primary colour correction in film post-production?
- A. To apply a stylised look that changes the mood of a scene
- B. To balance exposure, contrast, and colour across shots so they match ✓
- C. To add visual effects such as glows and light leaks
- D. To remove noise and grain from footage
Why: Primary correction adjusts the overall tonal and colour balance of a shot, ensuring consistency across footage before any creative grading is applied.
Q2. Which tonal range do lift, gamma, and gain controls primarily affect?
- A. Only the midtones
- B. Only the highlights
- C. Shadows, midtones, and highlights respectively ✓
- D. The saturation of the image
Why: Lift affects the shadows (darkest areas), gamma affects the midtones, and gain affects the highlights (brightest areas).
Q3. What does a waveform monitor display?
- A. The frequency of audio in the clip
- B. The luminance levels of the image across its horizontal width ✓
- C. The colour histogram of the sound mix
- D. The frame rate and compression settings
Why: A waveform monitor plots luminance values vertically against the horizontal position in the frame, helping colourists check exposure and levels precisely.
Q4. If a shot looks too blue overall, which adjustment would typically help correct it?
- A. Adding blue to the gain wheel
- B. Adding yellow or amber to the gain and gamma wheels, or moving the balance toward yellow ✓
- C. Increasing saturation across the image
- D. Lowering the lift on the blue channel only
Why: Blue cast is neutralised by adding its complementary colour, yellow/amber, which pulls the image back toward neutral white balance.
Q5. What is the purpose of the vectorscope in primary correction?
- A. To measure the audio levels of a scene
- B. To display the hue and saturation of the image, helping check colour balance and skin tones ✓
- C. To track motion between frames
- D. To show the resolution of the source file
Why: The vectorscope plots chrominance, showing hue as angle and saturation as distance from centre, which helps colourists judge colour balance and check skin tones against the skin tone line.
Module 4
Module 4: Secondary Colour Adjustments
Secondary Colour Adjustments
Knowledge check
Q1. In colour grading, what is the primary purpose of a secondary colour adjustment?
- A. To change the overall exposure of the entire frame
- B. To isolate and modify a specific range of colours or a defined area of the image ✓
- C. To add film grain to the footage
- D. To convert the clip from one frame rate to another
Why: Secondary adjustments target a specific hue, saturation, or luminance range, or a masked region, allowing you to modify those elements without affecting the rest of the image, unlike primary corrections which act on the whole frame.
Q2. Which tool is most commonly used to select a specific range of colours for a secondary adjustment?
- A. The lift wheel
- B. The gain wheel
- C. The qualifier (or HSL selector) ✓
- D. The sharpness slider
Why: A qualifier, sometimes called an HSL selector, lets you pick a range of hue, saturation, and luminance so that only pixels falling within those values are affected by your adjustment.
Q3. Why would a colourist use a power window in a secondary grade?
- A. To increase the resolution of the footage
- B. To apply a shape-based mask that limits adjustments to a specific area of the frame ✓
- C. To stabilise shaky camera movement
- D. To export the project in a different codec
Why: Power windows are shapes (circles, rectangles, or custom curves) that mask part of the image so that corrections such as brightening a face or darkening a sky only affect that region.
Q4. If you want to make the blue sky in a shot a deeper, richer blue without changing the skin tones, what is the best approach?
- A. Apply a global saturation boost to the whole clip
- B. Use a qualifier to isolate the blue hues and adjust only their saturation or luminance ✓
- C. Increase the gain wheel for all channels
- D. Lower the clip's opacity
Why: Isolating the blue range with a qualifier lets you adjust the sky independently, leaving the warm skin tones untouched, which a global adjustment would not achieve.
Q5. What does 'feathering' a mask or power window do?
- A. It adds a texture overlay to the image
- B. It softens the edge of the mask so the adjustment blends gradually into the surrounding image ✓
- C. It removes noise from the shadows
- D. It reduces the file size of the render
Why: Feathering blurs the boundary of a mask, creating a soft transition so that secondary corrections look natural rather than revealing a hard, visible edge.
Module 5
Module 5: Creating Look Development and Mood
Creating Look Development and Mood
Knowledge check
Q1. In colour grading, what is the primary purpose of establishing a 'look' for a film?
- A. To correct technical exposure errors only
- B. To create a consistent visual identity that supports the story's tone and mood ✓
- C. To remove all colour from the image
- D. To match every shot to a standard broadcast reference chart
Why: A look is a deliberate visual style applied across the film so that colour choices reinforce the narrative tone and emotional mood, giving the film a coherent identity.
Q2. Which colour temperature shift is most commonly associated with creating a cold, melancholic mood?
- A. Warm amber and orange tones
- B. Cool blue and teal tones ✓
- C. High-saturation magenta
- D. Neutral grey with no tint
Why: Cool blue and teal tones suggest coldness, distance, loneliness, or sadness, which is why they are frequently used to convey melancholic moods.
Q3. What does the term 'teal and orange' refer to in film colour grading?
- A. A camera sensor colour profile
- B. A popular complementary colour scheme where skin tones are warm and shadows or backgrounds are cool ✓
- C. A printing standard for film posters
- D. A lens coating that reduces glare
Why: Teal and orange is a complementary palette often used in cinema: warm orange tones flatter skin while cool teal tones in shadows and backgrounds create contrast and depth.
Q4. Why do colourists often use a consistent base 'look' across a whole film?
- A. To reduce the file size of the final render
- B. To ensure visual continuity so the audience perceives a unified world and story ✓
- C. Because audiences cannot see colour differences
- D. To avoid having to grade individual shots
Why: A consistent look maintains continuity between scenes and locations, helping the audience feel they are in one coherent cinematic world.
Q5. Which adjustment would most directly reduce the vibrancy of a scene to evoke a faded, nostalgic feel?
- A. Increasing saturation
- B. Lowering saturation and lifting the black levels ✓
- C. Sharpening the image
- D. Raising contrast to maximum
Why: Lowering saturation removes colour intensity, and lifting blacks creates a washed-out, matte appearance commonly associated with faded, nostalgic imagery.
Module 6
Module 6: Skin Tones and Continuity Matching
Skin Tones and Continuity Matching
Knowledge check
Q1. Which tool is most commonly used by colourists to check whether skin tones look natural across a scene?
- A. The histogram
- B. The vectorscope with its skin tone line ✓
- C. The waveform monitor set to RGB parade only
- D. The sharpness overlay
Why: The vectorscope displays chrominance, and most scopes include a skin tone indicator line. Healthy skin tones typically fall along this line, making it a quick reference for natural-looking skin across shots.
Q2. When matching continuity between two shots of the same actor, what should a colourist prioritise first?
- A. Making the background as vibrant as possible
- B. Matching the skin tone of the actor so it appears consistent ✓
- C. Increasing overall contrast to hide differences
- D. Applying a strong creative LUT to both shots
Why: Viewers are highly sensitive to changes in skin tone, so a face that shifts colour between cuts is immediately noticeable. Matching the actor's skin is therefore usually the top priority in continuity grading.
Q3. What is a common cause of unnatural skin tones in footage shot under mixed lighting?
- A. Using too high a frame rate
- B. Different colour temperatures from light sources, such as tungsten and daylight, on the same face ✓
- C. Recording in a compressed codec
- D. Shooting with a shallow depth of field
Why: When a face is lit by sources with different colour temperatures, one side may appear orange and the other blue. Colourists correct this by balancing the lights or using secondary corrections to unify the skin tone.
Q4. Which adjustment is typically the safest starting point when correcting a slightly too-green skin tone?
- A. Adding magenta in the midtones to offset the green cast ✓
- B. Increasing saturation across the whole image
- C. Lowering the black level significantly
- D. Adding blue to the highlights only
Why: Green and magenta are opposite on the colour wheel, so adding magenta neutralises a green cast. Targeting the midtones keeps the correction focused where skin usually sits, avoiding unwanted shifts in shadows and highlights.
Q5. Why do colourists often use a qualifier or secondary correction when grading skin tones?
- A. To change the frame rate of the clip
- B. To isolate the skin so it can be adjusted without affecting the rest of the image ✓
- C. To remove noise from the entire frame
- D. To convert the footage to black and white
Why: Qualifiers such as hue, saturation, and luminance keys let the colourist select only the skin areas. This allows precise adjustments to skin tone while leaving backgrounds, costumes, and other elements unchanged.
Module 7
Module 7: Delivery, Export and Final Review
Delivery, Export and Final Review
Knowledge check
Q1. Which color space is most commonly used as the working space for a final master intended for broadcast or streaming delivery in the Rec.709 standard?
- A. DCI-P3 with a 2.6 gamma curve
- B. Rec.709 with a 2.4 gamma curve ✓
- C. sRGB with a 1.8 gamma curve
- D. Adobe RGB with a 2.2 gamma curve
Why: Rec.709 is the standard HD broadcast and web delivery color space, and it is paired with a gamma of approximately 2.4 for display on standard televisions and monitors.
Q2. What is the main purpose of rendering a graded timeline to an intermediate format such as ProRes 4444 or DNxHR before final export?
- A. To reduce the file size to the smallest possible value for email
- B. To preserve color and quality by avoiding repeated compression during later steps ✓
- C. To automatically add subtitles and closed captions
- D. To convert the project frame rate to 60fps
Why: Intermediate codecs are high-quality, lightly compressed formats that prevent quality loss and banding when the graded footage is re-encoded or passed to other processes.
Q3. During final review, which tool is best suited to check whether a graded shot's luminance stays within legal broadcast limits?
- A. A histogram or waveform monitor ✓
- B. A color wheel adjustment panel
- C. A LUT library browser
- D. A noise reduction preview window
Why: Waveform monitors and histograms display the luminance distribution of an image, allowing a colorist to confirm that signal levels fall within legal ranges such as 0 to 100 IRE.
Q4. Why should a colorist review the final export on a calibrated reference monitor and on a consumer device?
- A. Because consumer devices always display more accurate color than reference monitors
- B. Because the image should look acceptable across the different displays the audience will actually use ✓
- C. Because the export codec only plays correctly on consumer devices
- D. Because reference monitors cannot display Rec.709 content
Why: Viewers watch on many different screens with varying calibration, so checking on both a reference display and a typical consumer device helps ensure the grade holds up in real viewing conditions.
Q5. Which file naming and metadata practice is most important when delivering a final graded master to a client?
- A. Naming files with random numbers so they cannot be copied
- B. Including a clear version name, date, and specification details such as resolution, frame rate, and color space ✓
- C. Deleting all project metadata to reduce file size
- D. Renaming the file to match the client's personal name only
Why: Clear version names and technical specifications allow clients and post-production teams to identify, verify, and correctly use the delivered master without confusion.
