Don't It Make Y our Brown Eyes Blue?

November 1997 / Eval / CMOS Gets the Picture / Don't It Make Your Brown Eyes Blue?

A digital camera tries to record colors the way the human eye sees them. Since the retina has three different color receptors (red, green, blue), you'd assume a camera also needs three receptors . Unfortunately, the dyes in a camera's sensors don't match the eyes' color response very well.
Sound Vision adds a fourth dye, teal. This extra measurement helps achieve a better color match. Interestingly, some women's eyes have four color receptors, a condition called tetrachromaticity. Some geneticists speculate that such women can better assess their children's health by skin tone.
