when under a red light.
Red Light
Because white light is made up of all the colors of the spectrum, and an object that appears red in color is simply reflecting the color red, a white object refects all the colors of the spectrum while black objects reflect no colors at all.
Reflected
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)
Our eyes only see the colours red, green and blue, in varying levels. It is our brain that converts combinations of these into the many millions of colours that we can perceive.An object that appears yellow under white light is reflecting colours that cause both our red and green cones (cells in our eyes that respond to colour) to fire. Note we have no yellow cones in our eyes.When the same object is placed under red light, then only red light is reflected from the object, and thus only the red cones respond, causing us to see the object as red.

Reflected
We see colours because of the light absorbed by the object in view. White paper absorbs all the colours of the rainbow - so only white is reflected. A red stop sigh absorbs all colours except for red & white.

answer ples
bcoz
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.
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.
The white object will look red because the white surface reflects all colors and since only a red light is used it will only reflect red.
Rigel is much hotter. Red is the lowest temp. blue and white are the hottest
