HLS.RdThis function creates colors of class HLS; a subclass of the virtual
color-class class.
HLS(H, L, S, names)These arguments give the hue, lightness, and saturation of the
colors. The values can be provided in separate H, L and
S vectors or in a three-column matrix passed as H.
A vector of names for the colors (by default the row names of
H are used).
An object of class HLS which inherits from class color.
This function creates colors in an HLS color space. The hues should lie between between 0 and 360, and the lightness and saturations should lie between 0 and 1.
HLS is a relative color space; it is a transformation of an RGB color
space. Conversion of HLS colors to any other color space must first
involve a conversion to a specific RGB color space, for example the
standard sRGB color space (IEC standard 61966).
