Build Status

Go port of HSLuv (revision 4), written by Michael Glanznig

More details about HSLuv at http://www.hsluv.org.

API

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.

hsluv.HsluvFromHex(hex)

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).
