Summary
Description Linear visible spectrum.svg |
English:
A linear representation of the visible light spectrum. Colour ranges were taken from 'CRC Handbook of Fundamental Spectroscopic Correlation Charts' (see
w:Visible spectrum
). Spectral XYZ locus coordinates were found
here
. Every 10nm, the spectral locus point was used as the initial point in a search for a matching sRGB colour (assuming "Dim" viewing condition). The search was carried out by a binary search along a line in CIECAM02 JCh space between the spectral point, and a point with 0.3 * brightness (J), 0 chroma (C), and the same hue (h) as the spectral point. The search finished when a point was found that was in sRGB space. The CAT02 matrix was modified as suggested in
Brill(2008)
to reduce yellow-blue problems by replacing the bottom row (0.0030, 0.0136, 0.9834) with (0,0,1). An iterative smoothing was carried out to eliminate the largest jumps in chroma (greater than 5% change). Code used to generate the colour gradient can be found
here
