Guys, I got a bug that I can't figure out. Please anyone can find a solution?
Error message: picturer:77: bad argument #1: value expected
Code: http://pastebin.com/4r4pPsTY
Thanks in advance!

You might be converting your hex numbers into decimal numbers incorrectly. Try using tonumber (hexNumber, 16) to convert the hex string into base 10 from base 16.

It did fix the problem, but now there's a weird bracket bug that I can't trace.

this line wasnt using parentheses properly

term.setBackgroundColor(2^tonumber(string.sub(bg[pi], pj, pj), 16))

if tonumber is returning nil then it means the string being passed to it is not valid hexadecimal. Make sure you're not giving it anything that wouldn't be valid hex.

Might be the problem, but it crashes when I try to change the BG color or text color in the editor. When I edit the numbers manually it shows the colors just fine.

FIXED. I switched the height with width, so I had '19' instead of '51'. Thanks for contributing everyone!
