A red object appears dark and almost black in green light because red objects absorb green light and do not reflect any light back to our eyes.
The red light would be absorbed by the green object and the object would appear dark. The green object reflects green light and absorbs other colors.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
A green light makes a red object appear black, because red objects absorb green light and do not reflect any visible light back.
The object will appear to be magenta because it reflects red light (which corresponds to the magenta color) and blue light, while absorbing green light.
Things appear red because they absorb all wavelengths of visible light apart from red this will be reflected. If you only shine green light on the object it will all be absorbed and no light will be reflected so it will appear black.

Green will be the color of a yellow object in a dark room while red light falls on it.

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. :)
An object appears green when it reflects green light and absorbs other colors from the visible light spectrum. This is due to the object's molecular structure, which determines how it interacts with light. When green light is reflected off an object, it is detected by our eyes as the color green.
Well, the grapes, if in a black room, will absorb off any colours that are not its colour. So the answer would be black. The green grapes would turn black if a red light was shone upon them. ^ hope i have helped!
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)
Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black. It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.
