From wavelength to RGB filter 81 In a more general way, Grassman’s law, for a given color with a spectral distribution power I(λ), can be expressed by the R G B coordinates given by: ∞ = λ λλ 0 R I()r()d; ∫ The human eye detects light in the range 380—780nm. The critical difference is that the hex system represents the numbers from 0 to 255 using just two characters. Star 9 Fork 1 Star Code Revisions 1 Stars 9 Forks 1.
