The lists are constructed either by parameters or by name.Colors by parametersdisplays systematic series of colors, based on 3-tuples of numbers that are interpreted as color parameters in the ‘rgb’, ‘cmy’, and ‘hsb’ color models.Colors by namedisplays sets of colors that have been given specific names such that LATEX users do not have to care about their parametrisation. However, as soon as there is the intention to use these colors outside the LATEX world (e.g. website construction or drawing programs), the parameters suddenly gain importance. For each color name, we display the color itself plus the name of the underlying model, a 50%-tint (mixture with white), a 50%-tone (mixture with gray), a 50%-shade (mixture with black), and thecomplementary color. Additionally, for the base colors defined by the xcolor package, also all 50%- mixes of base color pairs are included.Constantsused for model specification and conversions are \adjustUCRBG = 1,1,1,1 (‘cmy’ to ‘cmyk’ conversion); \rangeRGB = 255 (integer version of ‘rgb’), \rangeHSB = 240 (integer version of ‘hsb’), \rangeGray = 63 (integer version of ‘gray’). Please refer to the xcolor package documentation [1] for detailed explanations of the underlying models and algorithms.References[1] Uwe Kern: xcolor package, “LATEX color extensions”.
