| I would like to be able to convert RGB color codes into hex format.
I've tried this:
--works for black and white
print("#"..string.format("%06x", ColourNameToRGB("white"))) --> "#ffffff"
print("#"..string.format("%06x", ColourNameToRGB("black"))) --> "#000000"
--but for red, I get blue!
print("#"..string.format("%06x", ColourNameToRGB("red"))) --> "#0000ff"
Thanks!
[EDIT] okay so I figured out rgb color codes are actually bgr [/edit]
--this works :)
local function rgb_to_hex(col)
local b, g, r = string.match(string.format("%06x", col), "([0-9a-f][0-9a-f])([0-9a-f][0-9a-f])([0-9a-f][0-9a-f])")
return "#"..r..g..b
end
print(rgb_to_hex(ColourNameToRGB("yellow"))) -- > "#ffff00"
