LCHColor
LCHColor[l,c,h]
represents a color in the LCH color space with lightness l, chroma c and hue h.
LCHColor[l,c,h,a]
specifies opacity a.
LCHColor["string"]
returns a color from an HTML color name etc.
LCHColor[color]
returns the LCH representation of color.
Details


- LCHColor is a perceptual color space corresponding to a cylindrical transformation of LABColor with the a and b components represented in polar form in terms of c and h, allowing for easier interpretation of color parameters.
- LCHColor is device independent and corresponds to the CIE
color space with
.
- The parameters have the following interpretation:
-
l lightness, approximate luminance c chroma, color saturation h hue, cyclic color from red to yellow to green to blue ,
, and
where
, and
where
,
, and
are color parameters,
,
, and
are white point parameters in XYZColor, and
is a piecewise function that is equal to
for
and
for
.
- LCHColor allows any real number for l, c, and h.
- RGBColor approximately corresponds to l between 0 and 1, c between 0 and 1.3, and h between 0 and 1.
- ColorConvert can be used to convert LCHColor to other color spaces.
- The alternative forms LCHColor[{l,c,h}] and LCHColor[{l,c,h,α}] can also be used. »
- {LCHColor[…],p1,…} indicates that graphics primitives pi should be displayed in the color given.
- Style[expr,LCHColor[…]] specifies that expr should be displayed with the specified color. »
- For 3D surfaces, explicit LCHColor directives define surface colors; the final shading depends on lighting and contributions from specularity and glow. »
- Glow[LCHColor[…]] specifies color independent of lighting. »
- LCHColor[l,c,h,α] is equivalent to Directive[LCHColor[l,c,h],Opacity[α]]. »
- If no opacity has been specified, LCHColor[l,c,h] is equivalent to LCHColor[l,c,h,1].
