getBounds :: HSLuvLightness -> [Line]

For a given lightness, return a list of 6 lines in slope-intercept form that represent the bounds in CIELUV, stepping over which will push a value out of the RGB gamut.

maxSafeChromaForL :: HSLuvLightness -> LCHChroma

For given lightness, returns the maximum chroma. Keeping the chroma value below this number will ensure that for any hue, the color is within the RGB gamut.
