Luna moths are known for their striking bright green wings, which help them camouflage among leaves. This vibrant green color is distinctive to the species. Their wings also have eye spots and long tails, but the lime-green coloration is their most recognizable feature. Brown, white, and dull red are not characteristic of Luna moths.

Purple finches are actually crimson or rose-red in color, particularly the males during breeding season. The name is misleading - they are not purple. Females are brown and white, but males show the distinctive red coloration that gives them their name despite the color misnomer.

A green leaf appears green because chlorophyll reflects green light and absorbs other colors (red and blue). When illuminated with pure red light, the leaf absorbs the red light and reflects nothing. Without any reflected light reaching our eyes, we perceive the leaf as black.
