I need to change HEX to RGB.

I don't know how it works nor how it can be worked out, need a helping hand here.

Nevermind, i found it myself.

Like:

#1DFFAA 
  
R = 16(1+13/16) = 29 
G= 16(15+15/16) = 255 
B = 16(10+10/16) = 170

function hex2rgb(hex) 
  hex = hex:gsub("#","") 
  return tonumber("0x"..hex:sub(1,2)), tonumber("0x"..hex:sub(3,4)), tonumber("0x"..hex:sub(5,6)) 
end

Just in case anyone needs the opposite of this function:

function rgbToHex ( nR, nG, nB ) 
    local sColor = "#" 
    nR = string.format ( "%X", nR ) 
    sColor = sColor .. ( ( string.len ( nR ) == 1 ) and ( "0" .. nR ) or nR ) 
    nG = string.format ( "%X", nG ) 
    sColor = sColor .. ( ( string.len ( nG ) == 1 ) and ( "0" .. nG ) or nG ) 
    nB = string.format ( "%X", nB ) 
    sColor = sColor .. ( ( string.len ( nB ) == 1 ) and ( "0" .. nB ) or nB ) 
    return sColor 
end

    return sColor 
end 

eh

function rgb2hex(r,g,b) 
  return string.format("#%02X%02X%02X", r,g,b) 
end

hmm

 tocolor(r,g,b) 

?

tocolor() does not return hex color value as i recall. it's decimal with alpha.
