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 Edit

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).

```local function HexToRGB(hex)
local rhex, ghex, bhex
if strlen(hex) == 6 then
rhex, ghex, bhex = strmatch('([a-fA-F0-9]{2})([a-fA-F0-9]{2})([a-fA-F0-9]{2})', hex)
elseif strlen(hex) == 3 then
rhex, ghex, bhex = strmatch('([a-fA-F0-9])([a-fA-F0-9])([a-fA-F0-9])', hex)
if rhex and ghex and bhex then
rhex = rhex .. rhex
ghex = ghex .. ghex
bhex = bhex .. bhex
end
end
if not (rhex and ghex and bhex) then
return 0, 0, 0
else
return tonumber(rhex, 16), tonumber(ghex, 16), tonumber(bhex, 16)
end
end
