Thanks to @ilikelegos for the suggestion. Official Lego colours from http://www.ldraw.org/library/official/ldconfig.ldr If you want to use another pic you can use this project (. https://scratch.mit.edu/projects/66980580/ ) to scan a pic into a list. Use a resolution of 60x45. Export the list from that project and then import it into the "image" list over here.
