To make a red object look black is when you hold turn off the lights and hold a black light towards it.
BlackAll of the colours that make the white light shine down on the black object and all of the colours that make the white light the light absorbs into the object and no light reflects.WhiteAll of the colours that make the white light shine down on the white object and the light and no light is absorbed into the object but all of the colours that make the white light are reflected into your eyes
it would be black as there would be no color to reflect off of it e.g a green door in any color lighted room would make it look black except if it was in a white or green lighted room then it would look green :D
A blue object will appear black in red light because red light does not contain any blue wavelengths to reflect off the object's surface. Since the object does not reflect any red light, no color will be perceived.
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 black because it absorbs all the colors of the visible spectrum. If we idealize the object to make it perfectly absorptive, it absorbs all of the white light that strikes it and reflects none. In the real world, some light is always reflected. If the object appears black or dark gray, then it reflects small amounts of all colors of the spectrum.

When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.

If the light source is truly cyan, the red object should appear black. The object is red because it reflects the red portion of the white light spectrum. With no red wavelengths available to be reflected, the object will have a lack of color (i.e., black).
The green-colored object will appear dark and almost invisible in a black room, as it will not reflect or absorb much light without any light source to illuminate it. The lack of contrast between the object and the room will make it difficult to see.
A green light makes a red object appear black, because red objects absorb green light and do not reflect any visible light back.
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!
Any light that does not contain the primary color red will make the sheet of paper look black. (for example green, blue, cyan,... but not yellow, violet,...) This is because the surface of the sheet is such that it absorbs all the colors of white light except red which is reflected and which is why it appears red in white light.
