Question

In which colour does the grass ( green ) appear if the background light is red ?

Answer 1

Answer:

Like many plants, most species of grass produce a bright pigment called chlorophyll. Chlorophyll absorbs blue light (high energy, short wavelengths) and red light (low energy, longer wavelengths) well, but mostly reflects green light, which accounts for your lawn's color.

Answer 2

green and red mix looks like a brown colour
