 -- passing a table like {255, 100, 20} function application:rgbToHex(rgb) local hexadecimal = '0X' for key, value in pairs(rgb) do local hex = '' while(value > 0)do local index = math.fmod(value, 16) + 1 value = math.floor(value / 16) hex = string.sub('0123456789ABCDEF', index, index) .. hex end if(string.len(hex) == 0)then hex = '00' elseif(string.len(hex) == 1)then hex = '0' .. hex end hexadecimal = hexadecimal .. hex end return hexadecimal end

Thanks

im kinda noob at coding but here is my solution:

```rgb = {235,123,175}
function convert_to_hex (rgb)
local hex = ""
for i = 1 , #rgb do
local hex_table = {"0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F"}
local num =  rgb[i]/16
local whole = math.floor( num )
local remainder = num - whole
hex = hex .. hex_table[whole+1] .. hex_table[remainder*16 + 1]
end
return hex
end

print(convert_to_hex(rgb))
```

That's a frightening piece of code you wrote up there
