Why is it called a "black" ball in the first place ? Most likely because it absorbs
any light that hits it, regardless of color, and nothing ever bounces off of it.
That reasoning gives you your answer right there: You can shine red light on it ...
or green or purple or fuschia, mauve, burgundy, teale or turquoise ... and it'll still
look 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.
It would appear to be red because it can only reflect the red light.
Yellow as white objects reflect the whole visible light spectrum. So the white ball would reflect the yellow light.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.

Black is technically not a colour, merely an absence of colour. Light consists of seven colors, the object which will absorb all colors look black.

Maroon and black are dark colors, so try pairing them with light colors. Cream and light turquoise complement maroon and black.

It will turn it light brown apperently.
