The reason a black object is described as "a black object" is becasuse even
under white light, where every color is available, the thing absorbs all of them,
and doesn't reflect any color. Illuminating it with light of only a single color isn't
going to change that. It'll still appear black.
An object that appears yellow under white light will have a tendency to maintain its distinctly yellow appearance when bathed in yellow light.
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.
If the light is or contains the colour the object it is striking, then the object will appear to be the colour it originally is. If the light is not or does not contain the colour the object it is striking, then object will appear black. This is because an object will only reflect the light that is the same colour as it, all other light is absorbed. For example: Red, yellow, magenta, and white light will make a red object appear red as they all contain red light. Blue, green and cyan light will make a red object appear black.
An object appears a certain color to you because it reflects that color of light and absorbs other colors of light. For example, a white object appears white because it reflects all colors of visible light (red, orange, yellow, green, blue, indigo, violet). A black object appears black because it absorbs all of these colors--and as a result, none of those colors are reflected back to your eyes. Under white light, the object appears yellow-green because it reflects both yellow and green light and absorbs all other colors. (Remember, white light has all colors of visible light in it). If only green light is present, there's only green light for it to reflect--so it will appear green. If you shined yellow light on it only, it would be yellow. If you shined yellow and green light, it would appear yellow-green again. It you shined red and blue light on it, it would appear black, because it absorbs both of those colors.

Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.

yes it does
If the light is or contains the colour the object it is striking, then the object will appear to be the colour it originally is. If the light is not or does not contain the colour the object it is striking, then object will appear black. This is because an object will only reflect the light that is the same colour as it, all other light is absorbed.

it will be 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.
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect
It would appear black because the object would not reflect any of the colors of light back.
It would look like a very, very, very, very yellowy orange.
