For exactly the reason that you call it a "a green object". You describe it that way

because most of the time, when it's being illuminated by light of all colors, the only

color that it does NOT absorb, and that remains to bounce off of the object and be

seen by your eye, is the green. When there is no green light striking the object, it

can't reflect any light to your eye, and it appears black.

A green object is called "green" because that's the only color of light that it reflects to our eyes, while it absorbs any other light. If there's no green light shining on it, then there's nothing for it to reflect, and we would describe it as a "black" object under those conditions.

### What colour would a green object look under a red light and why?

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. :)
