How do they remove the pigment?
"...Therefore, the only method of making purely white paint is to use a single compound that reflects red, green and blue light, which appears white to the human eye.
However, in additive color mixing, in which wavelengths are emitted rather than absorbed, the opposite is true. If red, green and blue spotlights converge on the same spot, their combination is white. This principle is used in televisions, fluorescent lamps and computer monitors."
"...You might think white paint doesn't contain any color so it doesn't need any pigment. Actually, it needs as much pigment as any other paint. Titanium white paint is so-called because it's made with titanium dioxide pigment."
