Question

Which of the following statement(s) is/are TRUE regarding color theory:

• A. Subtractive color theory is used for color printing
• B. Additive color theory is used to display images on a color television screen
• C. White light projected on a translucent filter made of yellow dye would subtract the blue light
• D. White light projected on a translucent filter made of cyan dye would subtract the green light

Hint:

Additive (RGB) $⇒$ emit light (screens). Subtractive (CMY[K]) $⇒$ absorb light (pigments/printing). Yellow removes blue; cyan removes red; magenta removes green.

Answer 1

The Correct Option is A

(A) True. Color printers use the subtractive model (CMY/CMYK): inks subtract components of white light.
(B) True. Displays/TVs use the additive model (RGB): light from primaries adds to form colors.
(C) True. A yellow filter transmits red + green and absorbs (subtracts) blue.
(D) False. A cyan filter transmits green + blue and absorbs red, not green.
