← User defined functions < HexToRGB
Takes a hex string (must be 6 char long!) and converts it to a RGB set (0-255)
local function HexToRGB(hex) local rhex, ghex, bhex = string.sub(hex, 1, 2), string.sub(hex, 3, 4), string.sub(hex, 5, 6) return tonumber(rhex, 16), tonumber(ghex, 16), tonumber(bhex, 16) end
Alternative version[]
Takes a hex string (must be 3 or 6 chars long!) and converts it to a RGB set (0-255). If hex is invalid, return black (0,0,0).
