This cmyk color picker is an extension of the RGB color picker, but it uses cyan, magenta, yellow and black inks to create the desired colors. The cmyk color picker was created because there are some colors that can only be produced with CMYK ink.The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
