Detailed Description
A qualitative HCL palette is constructed in a 3D color coordinate space with coordinates named Hue, Chroma, and Luminance, where the coordinate Hue can have an arbitrary value, and coordinates Chroma and Luminance are constant: hue = hue1 + i * (hue2 - hue1) chroma = const luminance = const where i is a value (of intensity or interestingness) based on which the colorization should be done.

SBDColorPaletteQualitative::getColorInPaletteColorSpace - Computes color coordinates color in the HCL color space for the given intensity value value.
- Parameters
-
color - an array for color coordinates (float[3]) in the HCL color space. value - an intensity value based on which the resulting color is computed, the intensity value should be in range [0.0, 1.0] where 1 corresponds to the full intensity.
