It is either green because the colour of light above it is the only colour it allows through like in this case Green light only lets green through or it could be cyan as blue and green make cyan but i think it would be green
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.
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.
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.
Red Light
light purple
The cloth would be wite because if it were any other color the colored light would mix with the color of the cloth and make a different color.
red orange
Black because green light is absorbed by the blue sky
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 and purple light.
