Convert image pixel data to one big string

Question

I am looking to take an input of an image then look through every pixel and see which of 60 colors in a tuple(which each have a character corresponding to it) it is closest to, then add that character of the color to a string.

#rgb values of each color with the character it is

RecRoomColors = [
    (191, 74, 84, 'a'),
    (179, 24, 45, 'b'),
    (107, 11, 38, 'c'),

Answer 1

You can use a dictionary where its keys will be the pixels and the values the characters. Your code would be:

RecRoomColors = {
    (191, 74, 84): 'a',
    (179, 24, 45): 'b',
    (107, 11, 38): 'c',
    ... # you have to complete here the rest of the values
    (18, 20, 41): '2',
}
