It absorbs all colors except red.
A transparent red object transmits red light and absorbs all other colors of light. This is because the object appears red when red light is transmitted through it, while all other colors are absorbed.
Dark colors absorb more light because they contain pigments that are better at absorbing light energy. When light hits a dark-colored object, the pigments in the object absorb the light rays instead of reflecting them, making the object appear darker.
Blue objects absorb all colors of light except for blue. When light hits a blue object, the object absorbs the other colors within the visible spectrum, reflecting or transmitting the blue light.
When you put an object in front of light, the object can either absorb, reflect, or transmit the light. If the object absorbs the light, it appears dark. If it reflects the light, it appears illuminated. If the object transmits the light, it may appear transparent or colored.
White light contains the many colors you see. The illuminated object will absorb and reflect the light as its' materials see fit. A black object will absorb all colors. A white object reflects all colors. Everything else lies in between there somewhere.
Colored objects absorb some colors of light and reflect others. When you shine a colored light on an object, the object will absorb the light colors it matches and reflect the colors that it does not. This interaction between the object's color and the light color leads to the object appearing to be a different color under different colored lights.
A blue object absorbs most colors of light but reflects blue light, which is why we perceive it as blue.
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.
a blue object reflects blue it absorbs the rest of the colors
If an object absorbs all the colors in white light, it reflects black.
An object that is black or very dark in color will typically absorb the most light because dark colors absorb light rather than reflecting it. Additionally, objects with rough surfaces or materials that specifically absorb light rays across a broad spectrum will also absorb more light.
A blue filter absorbs most colors of light except blue, which it transmits. This means that it will absorb red, green, and other colors of light, while allowing blue light to pass through.
