hsluv.HsluvToHex(hue, saturation, lightness)
hue is a number between 0 and 360, saturation and lightness are numbers between 0 and 100. This function returns the resulting color as a hex string.
hsluv.HsluvlToRGB(hue, saturation, lightness)
Like above, but returns 3 numbers between 0 and 1, for the r, g, and b channel.
Takes a hex string and returns the HSLuv color as 3 numbers for hue (0-360), saturation (0-100) and lightness (0-100). Note: The result can have rounding errors. For example saturation can be 100.00000000000007
hsluv.HsluvFromRGB(red, green, blue)
Like above, but red, green and blue are passed as numbers between 0 and 1.
Use HpluvToHex, HpluvToRGB, HpluvFromHex and HpluvFromRGB for the pastel variant (HPLuv).
