Answer 1

Magenta paints absorb green light.

Cyan paints absorb red light.

Yellow paints absorb blue light.

therefore

a) when blue is incident (cyan + magenta) both will reflect blue so will look blue

b) when green is incident (yellow+magenta) will absorb green light and no light will be reflected so will look black.

c) when red is incident (magenta + yellow) will absorb green and blue but incoming light does not have either green or blue so it will look red

d)when yellow is incident (cyan pigment) will absorb red so it will look (R+G-G=G) green.

e)

f) when cyan is incident magenta pigment will absorb green light and will look blue.
