red
If you put a piece of white paper under a green light all that will happen is the paper will turn green. The only time this will vary is if you have special ink that will show up under certain colored light.
The white paper appears red under a red light because the paper is reflecting and absorbing certain wavelengths of light. When red light shines on the paper, the paper reflects the red light and absorbs other colors, making it appear red.
It would appear black because the object would not reflect any of the colors of light back.
The yellow cloth would appear dark under cyan light, as cyan light absorbs yellow. It would appear brownish-gray under blue light, as blue light is the opposite of yellow on the color wheel and would cancel it out.
Why do you call it a "white object" ? Could it be because it looks white under white light ... light composed of every color ? Well then, the object must reflect every color. So it appears to be the color of whatever light you illuminate it with. Yellow under yellow light, etc.

The red pigment in the paper will absorb all colors except red, which will be reflected. When yellow light shines on the paper, which contains red pigment, the red pigment will absorb the other colors in the yellow light spectrum but reflect the red light. So, the paper will appear red under yellow light.

it would appear black because no red light strikes it

When a green apple appears black under a red light, it is because the red light does not contain wavelengths that correspond to the green color of the apple. The red light is absorbed by the apple, causing it to appear black as there is no green light being reflected off the surface to be perceived by our eyes. Each color of light corresponds to a specific wavelength, and when the light's wavelength does not match the object's color, the object will appear different.
all colors except red will appear black in red light
Sperm may appear whitish or yellow under UV light due to the presence of fluorescent molecules in semen.
The object will appear white because it reflects all colors of light equally, resulting in a white appearance.
