I live in Paris, France.

I work on video games (computers and consoles) for a living. I write free software and all kind of crazy shit for fun. My interests: image processing, video coding, rendering, game development, maths, physics, compression, cryptography.

comment Is it possible that there is a color our human eye can't see?
@MooingDuck Well maybe because of how addition and scalar multiplication work in a Hilbert space? Who knows! But yes, it is exactly how things work. The CIE-1931 standard defines three x/y/z base colour matching functions and the projection of a combination of lightwaves onto this base uniquely defines the chromatic response. You can read more about CIE-RGB and CIE-XYZ here.

The gamut of visible colours for trichromats is not a convex triangle. Our TV screens fail to display about half the colours visible by humans. The reason three colours are sufficient is because our brain accepts the information loss. Also your assumption that two colours would be enough for dichromats is rather oversimplifying.

And some colours do not even have a pure wavelength, eg. magenta.
