Hello, i need help.

I know what is "getColorFromString"

Example:

color = "#00FF00" 
r, g, b = getColorFromString(color) 
-- result: 0, 255, 0 

but my question is how i can to hex of RGB?

Example:

color = "0, 255, 0" 
-- result: 00FF00

local r,g,b = 0,255,130 
local n1 = toHex(r) 
local n2 = toHex(g) 
local n3 = toHex(b) 
  
function toHex ( n ) 
    local hexnums = {"0","1","2","3","4","5","6","7", 
                     "8","9","a","b","c","d","e","f"} 
    local str,r = "",n%16 
    if n-r == 0 then str = hexnums[r+1] 
    else str = toHex((n-r)/16)..hexnums[r+1] end 
    return str 
end
