L*u*v* or its cylindrical-coordinate cousin L*t*theta* (or LCH_uv). "Choosing Color Palettes for Statistical Graphics" is a nice paper talking about an implementation in R (although they do seem to misname L*t*theta* as HCL, which officially is different): http://eeyore.ucdavis.edu/stat250/epub-wu-01_abd.pdf For the "real" HCL, which also might be useful: http://mmis.doc.ic.ac.uk/mmir2005/CameraReadyMissaoui.pdf The main problem with perceptual colorspaces is that they do not map neatly to the color gamut of the RGB or CMYK colorspaces of typical rendering devices. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
