Practice question · Match the pairs
Match each term to what it names.
- Additive mixing
- Subtractive mixing
- Chroma
- Value
- How much light a surface returns, on a scale of 0 to 10
- Combining filters, so that the fractions multiply
- Distance from a neutral grey of the same lightness
- Combining emitters, so that the powers sum
Hints
- Two of the four name operations and two name dimensions of a colour.
- One of the dimensions is measured against a neutral.
Show the answer
- Additive mixing → Combining emitters, so that the powers sum
- Subtractive mixing → Combining filters, so that the fractions multiply
- Chroma → Distance from a neutral grey of the same lightness
- Value → How much light a surface returns, on a scale of 0 to 10
Why
Keeping these four apart disposes of most palette confusion. The two operations differ in arithmetic, not in kind; the two dimensions differ in what they are measured against, chroma against a neutral of equal value and value against black and white.
