A red object reflects red light and absorbs other colors of light. When white light shines on a red object, all the colors of the spectrum are absorbed by the object except for red, which is reflected back to our eyes.

What colour would a red object seem to look like if you only shined green light on it?

The object would be black, because red cannot reflect green light so no colour is reflected of the object.


What colour would a red object look under a red light?

The red object would appear red under a red light because objects primarily reflect the color of light that is shining on them. Since red light contains mainly red wavelengths, the object would still reflect red light and appear red.


What colour is a white object under red light?

A white object under red light will appear red. This is because white objects reflect all wavelengths of visible light, including red light, while absorbing little to no light. The white object will reflect the red light, giving it a red appearance.


What colour is a red object in green light?

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.


Why do red object's look black in blue light?

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.

What colour will a blue object look in red light?

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.


What colour does a green light make a red object?

A green light makes a red object appear black, because red objects absorb green light and do not reflect any visible light back.


What colour will a yellow object look in red light and why?

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)


Can object reflect both red and blue light?

On stage in a theatre red light shines and clothes appear red, blue light is shone an clothes appear blue, what colour are they?


What happens to a red object when light is shone on to it?

When red light shines on a red object, the object will reflect the red light and appear red. If white light shines on a red object, the object will absorb all colors except red, which it will reflect, making it appear red as well.


An object appears blue when seen in white light What colour will appear in Red light?

The simple answer is black. However, this is true only if the colour of said object is pure blue; If it has even the slightest tinge of red in it, you will see a very dark shade of red.


What colour will a white object appear if only red light was shone on it?

Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.
