Why can paint mix to become different colors? Don’t we see color by how light reflects off the material?
In: 5
There are multiple reason:
1.the combination of the pigments(molecules or small particles)that each reflects at the same time. This Mix of different light is than the colour.
2. The mixture reacts to a new kind of molecule or particle wich itself reflects only in one colour.
3. Combination of above
Yellow paint is full of molecules that absorb most wavelengths of light, but reflects yellow light. Blue paint is full of molecules that absorb most wavelengths of light, but reflects blue light. Mix them together, and now you have some yellow-reflectors and some blue-reflectors in the mixture. Now, when light shines on the mixed paint, some of it hits yellow-reflector molecules and some of it hits blue-reflector molecules, so some yellow light and some blue light gets reflected. This yellow light and blue light enters your eyes, which activates light-detecting cells. These cells respond the same way to a mixture of yellow and blue light as they do to pure green light, so your brain can’t tell the difference between a blue-yellow mixture and green. So, your brain interprets the color as green.
