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.
The red object would appear black because it would not reflect any of the green light shining on it. Green light is the complementary color of red, meaning the object would absorb all the green light and not reflect any color back to our eyes.
Green light - Green, White light - Green, Red light - Black
A green object under green light would appear its original color and shade of green. When an object is illuminated by light of the same color, no new colors are absorbed or reflected, resulting in the object appearing unchanged.
White light minus green light would appear as a purplish color. This is because when green light is removed from white light, the remaining color components combine to create a mix of blue and red light, which results in a purplish hue.
It would appear black because the object would not reflect any of the colors of light back.
Green.

Green.
it would appear black.
A lemon would appear green under green light because the object reflects the color of light that it does not absorb. In this case, a lemon's yellow color would absorb all other colors except green, which it would reflect.

In red light, a green apple would appear dark or black because red light contains wavelengths that are opposite to green on the color spectrum. This causes green objects to absorb the red light and reflect very little, resulting in a dark appearance.
The blue sky would appear green under green light because the green light would dominate the color seen by our eyes. The color of the sky is determined by the light that is reflected off of it, so when green light is shone on a blue sky, the green light will be the dominant color that is reflected.
green. The green is the only color not absorbed and therefor bounces off the shoe creating a green appearance
