What colors of white light does a blue object absorb?

A blue object absorbs white light that contains all colors except blue. When white light shines on a blue object, the object appears blue because it reflects blue light and absorbs all other colors in the white light spectrum.


What color will a white object be under a blue light?

A white object under a blue light will appear blue. However, your brain knows that the light is blue, and takes that into account when interpreting the scene. You'll probably still "know" the object is white. It's possible for stage technicians to take advantage of this and make you think that blue objects are white, by lighting them with blue light. (This is more common with red and green: lighting a green object with green light makes you think it's white; lighting it with red light will make it look black instead. This is a way to suddenly reveal figures that had previously been hidden on stage.)


Why does a blue object look blue under white light?

A blue object appears blue because it reflects blue light wavelengths and absorbs other wavelengths of light. When white light, which contains all colors of the spectrum, shines on the object, the blue wavelengths are reflected while all other colors are absorbed, resulting in the perception of blue color.


Why does an object appear blue in white light?

An object appears blue in white light because it absorbs all of the colors in the visible spectrum except blue, which it reflects. The reflected blue light is then what we perceive with our eyes as the color of the object.

Why does a white object look white in white light?

Why does a blue object illuminated by white light appear to be blue?

When white light shines on a blue object, the object absorbs all colors except blue, which it reflects. Our eyes perceive the reflected blue light, making the object appear blue to us. This happens because different colors of light have different wavelengths, and blue wavelengths are reflected while others are absorbed.


Why an object that is blue in white light would appear grey or black in green light?

An object that appears blue in white light does so because it absorbs all colors except blue, reflecting blue light. However, in green light, which does not contain any blue light, the object cannot reflect blue light and would therefore appear grey or black as it does not have any other color to reflect in the green light.
