is a color directive with lightness l and color components u and v.


specifies opacity α.


  • LUVColor is a color space designed to have perceptual uniformity; i.e. equal changes in its components will be perceived by a human to have equal effects.
  • LUVColor is device independent and corresponds to the CIE 1976 color space with .
  • The parameters have the following interpretation:
  • llightness, approximate luminance
  • The parameters , , and are given by , TemplateBox[{u, *}, Superscript]=13 TemplateBox[{L, *}, Superscript] (4 x/(x+15 y+3 z)-4 x_n/(x_n+15 y_n+3 z_n)), and TemplateBox[{v, *}, Superscript]=13 TemplateBox[{L, *}, Superscript] (9 y/(x+15 y+3 z)-9 y_n/(x_n+15 y_n+3 z_n)), where , , and are color parameters, , , and are white point parameters in XYZColor, and is a piecewise function that is equal to for and for .
  • LUVColor allows any real number for l, u, and v.
  • RGBColor approximately corresponds to l between 0 and 1, u between and 1.76 and v between and 0.88.
  • ColorConvert can be used to convert LUVColor to other color spaces.
  • The alternative forms LUVColor[{l,u,v}] and LUVColor[{l,u,v,α}] can also be used. »
  • {LUVColor[], p1, } indicates that graphics primitives pi should be displayed in the color given.
  • Style[expr,LUVColor[]] specifies that expr should be displayed with the specified color. »
  • For 3D surfaces, explicit LUVColor directives define surface colors; the final shading depends on lighting and contributions from specularity and glow. »
  • Glow[LUVColor[]] specifies color independent of lighting. »
  • LUVColor[l,u,v,α] is equivalent to Directive[LUVColor[l,u,v],Opacity[α]]. »
  • If no opacity has been specified, LUVColor[l,u,v] is equivalent to LUVColor[l,u,v,1].
