This graphic shows what color will be perceived when a material absorbs in certain regions of the visible spectrum….Complementary Colors.

Because yellow light is a mixture of red and green light, yellow will also reflect red and green light. Yellow does not contain blue, so it will appear black under blue light. White objects reflect all light, so will appear to be the colour of the light on them.

If by “yellow light”, you mean a light with wavelength between 560 and 590 nm, and by “blue paper”, you mean paper that reflects light only if its wavelength is between 450 and 490 nm, then yes, if the only illumination for a piece of blue paper is yellow light, it will appear black.

The color of light absorbed by a pigment is merely the complementary color of that pigment. Thus, pure blue pigments absorb yellow light (which can be thought of as a combination of red and green light). Pure yellow pigments absorb blue light.

black

A solution that looks yellow absorbs light that is violet, which is roughly 410 nm from the color wheel. Since it absorbs high energy, the electrons must be raised to a higher level, and Δo is high, so the complex is likely to be low spin.

So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy….Visible Spectrum.

The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. It reflects yellow light and we see it as yellow. The eye also uses complementary colors in color vision. When a color is removed from white light we see the complementary color.

A mixture of red and green light stimulates the red and green receptors on the retina of your eye. Those same receptors are also stimulated by yellow light! When the red and green receptors in your eye are stimulated, whether by a mixture of red and green light, or by yellow light alone, you see the color yellow!

A red ball reflects red color and absorbs the rest colors.So,if I throw green light on a red ball the ball will absorb that green light. Now,will the part on which the light falls must appear black as it absorbs all the light and reflects no light.

When we look at an object and see its color, we are seeing all of the light that reflects off of that object. Red objects reflect red light, green objects reflect green light, and so on. But what happens to the rest of the colors that hit that object? They get absorbed!

Because the green surface absorbs all colours other than green, no light at all is reflected from the object. No light enters the observers eye, so the object appears a black colour. The surface reflects the red and blue components, but absorbs the green component.

A Green object will ABSORB its complement (Magenta = Red + Blue). So, since Red light is ABSORBED by the Green pigmented object, NO LIGHT reflects back to your eyes, thus you “see” black.

Answer: they’ll be black, because green absorbs red.

It has to do with how paints works. Pigments absorbed certain colors, while light provides those colors. If we mix these two substances together, we get something that absorbs red, green, and blue light – making it black. (In reality, you get some other color like brown depending on the nature of the actual paints).

Mixing primary colors creates secondary colors If you combine two primary colors with each other, you get a so-called secondary color. If you mix red and blue, you get violet, yellow and red become orange, blue and yellow become green. If you mix all the primary colors together, you get black.
