Even though youv'e given it the name "Yellow", the object is only yellow
when there's some yellow light shining on it. You see, it absorbs all other
colors of light, and only yellow light bounces off of it. That's why the light
from that object that enters your eye is yellow light, and that's why you
describe the object as looking "yellow".
If there's no yellow light shining on the object, it looks black.
it will look green
Green
It will look red. White light is made up of a spectrum of many colours. The primary colours are red, green and blue. An object (in white light) appears yellow because it reflects red and green light but absorbs blue light. In red light, the same object will simply reflect the red light. Since there is no green light, the object will appear red. (A mixture of red and green gives yellow)
An object that appears yellow under white light will have a tendency to maintain its distinctly yellow appearance when bathed in yellow light.
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.

black
Dark green.A more descriptive answer:It depends on the exact spectra the light emits, not just what it looks to us.If the light combines red and green wavelengths, then the green object will appear green, because of the green wavelength. The object may have a yellowish tinge because of small reflection of the red wavelength.If the light is spectral yellow and not just red + green, then the green object will appear a much darker green maybe with a slight yellow or dark-yellow tinge because of, again, small reflection of dominant yellow wavelength.

violet, becasue of how the colours react to each other and how they work together to form green.

The object has absorbed light in the whole visible spectrum. For example, an object appearing blue in the white light has absorbed red, orange, yellow, green, indigo, and violet; but the blue light is reflected to your eyes. ==========================================
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.
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. :)
Yellow-green, or lime.
