How to remove HEX from nickname (#RRGGBB)

[H5N1]

Hello. I made mysql register system but I want to remove HEX code (RRGGBB) from nicknames. How can i do it? Some time ago I saw simple function which was removing HEX code, but I cant find it now.

function removeHEXFromString(str) 
str:gsub("#%x%x%x%x%x%x", "") 
end

Add 'return' in front of str:gsub, otherwise there won't be a new string returned

forgot that.

function removeHEXFromString(str) 
return str:gsub("#%x%x%x%x%x%x", "") 
end
