A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)
it would appear black because no red light strikes it
Black absorbs light rays easily and absorbs all colors, making you feel hotter if you wear black. However, white doesn't absorb light rays and reflects all colors, so you might prefer to wear that or another light color such as lime green, pastel blue, or pink on a hot day. On the other hand, on a chilly winter day dark colors would be the smart choice.
Yes, it does. If it didn't, it would appear black.
it will look black because the red object only reflects red light and so when green is shone on it cant reflect any so it appears black.
While the ball would still be green it will appear black. Anything green absorbed all colours except green. The green light is reflected to your eyes which makes it look green. Thus in red light (with no green in it) the red will be absorbed and no green light can be reflected to your eyes so the ball will look black.
If no other light was in the room then the hat would look very dark or black
Green light - Green, White light - Green, Red light - Black
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect

A purely green apple would look black under purely red light. If the apple were not purely green, it would look dark red. If the light were not purely red, the apple would look dark green. This is because red light does not reflect off purely green objects, and it is the reflected light which we see.
If there was only green light, then everything would be a hue of green (includes black, white) or a shade of grey. A cyan ball would appear as a muted grey-green, I would assume.
