The IPT color space of 1998 uses new data about hue to greatly improve on CIELAB's non-constant lines of hue, although it still leaves much to be desired in its prediction of colorfulness and lightness. For a standard dynamic range and a fixed viewing condition, it turns out that CIELAB's simple structure suffices as long as better coefficients are used. ![]() Even under the default reference viewing condition, CIELAB is known to poorly work in blue hues. In addition, the performance of the 1976 color spaces under different viewing conditions is not their only problem. ![]() ![]() A range of increasingly complex color appearance models appeared to model the behavior of human vision under different viewing conditions, but ended up less used due to the added inputs required and overall algorithmic complexity. HSLuv preserves the lightness and hue components of CIELUV LCh and stretches its chroma so that every color has the same range, defined as a percentage.ĬIELAB and CIELUV are soon recognized to be insufficient to explain the entire range of color phenomena. ![]()
