OpisSpectre visible lineaire en longueur d onde.png |
English: A linear representation of the visible light spectrum, French caption.
Français : Une représentation libéaire en longueur d'onde du spectre lumineux visible. Les gammes de couleurs sont issues du CRC Handbook of Fundamental Spectroscopic Correlation Charts (voir w:Visible spectrum). Les coordonnées spectrales XYZ sont tirées du CIE.
Tous les 10 nm, le point spectral est utilisé pour rechercher la couleur sRGB correspondante (en considérant la condition de visualisation "Dim", tamisé). La recherche se fait par une recherche binaire le long d'une ligne dans l'espace TSL entre le point spectral, et un point avec une luminosité de 0.3 * luminosité (L), une teinte 0 (T), et la même saturation (S) que le point spectral. La recherche se termine lorsque le point se trouvve dans l'espace sRGB. La matrice CAT02 a été modifiée comme suggéré dans Brill(2008) pour réduire le problème jaune-bleu en remplaçant la ligne du bas (0.0030, 0.0136, 0.9834) par (0,0,1). Un lissage itératif a été appliqué pour gommer les grands sauts de teinte (changements supérieurs à 5 %). Le code utilisé pour générer le gradient de couleurs peut être trouvé ici.Esperanto: Koloroj videblaj
