I was wondering whether the colours present in the game will be counted on the basis of each scene or the whole game, What if I am using only 2 colours per level (let's say black and blue, black and red) now will it be counted as 2 colours or a total of 3 colours (black, red, blue) Keep in mind that each level will only have 2 colours.

i mean theres an faq section that says switching between palettes is allowed, i think thats pretty self explanatory
