Examples
local rgb = color.packRgb(255, 0, 0)
local index = color.rgbToPalette(rgb) -- Returns palette index 35
local r, g, b = color.paletteToRgb(index) -- Returns 255, 0, 0
local h, s, l = color.rgbToHsl(r, g, b) -- Returns 0, 255, 128
h = 170 -- Makes a blue-ish color
r, g, b = color.hslToRgb(h, s, l) -- Returns 1, 1, 255
index = color.rgbToPalette(r, g, b) -- Returns palette index 152
hex = color.rgbToHex(r, g, b) -- Returns #0101FF
hex = color.rgbToHex(r, g, b, 128) -- Returns #0101FF80
hex = "#09C" -- Some very light blue
r, g, b = color.hexToRgb(hex) -- Returns 0, 153, 204
index = color.rgbToPalette(hex) -- Returns palette index 135
index = color.rgbToPalette("#0099CC") -- Same as above
index = color.rgbToPalette("#FA0") -- Some orange-ish color
index = color.rgbToPalette("FA0") -- Same as above
index = color.rgbToPalette("FFAA00") -- Same as above
