ITPEC IP October 2019 Question 24
ITPEC IP October 2019 — Question 24 of 100
Ideally, mixing cyan, magenta, and yellow pigments by subtractive color mixing produces black. Each pigment absorbs different components of white light; together they subtract red, green, and blue components, leaving no reflected light in the ideal model.
Answer (c)
Why not others:
- blue, red, and green result from other combinations or from the additive RGB model
- real printers add separate black ink because actual CMY inks often produce a muddy dark color rather than a clean, economical black
Key rule: Additive RGB combines light toward white; subtractive CMY combines inks toward black.
