anyways a colourset is basically just a list of named sets of colours (ie 1.000 1.000 1.000 1.000 or 255 255 255 255 would be white)
at the end of the sets of colour codes, you have a line that says "DIV: rowname" which is what names what each row on the spraycan interface is basically
example of a row
255 0 0 255
255 36 0 255
255 127 0 255
255 255 0 255
0 200 0 255
0 255 255 255
0 127 255 255
0 0 255 255
255 255 255 64
DIV: Standard
tell me if there are any issues with this because i wrote this when tired and so the quality of the explanation may be a bit bad
