Hey guys, I wanted to write a script that will halve hex colour values and add together all possible combinations from 16 colours, making 256 colours. I suppose I could just halve the values to begin with, so really all I need to do is add hex value together to create all possible combinations. I have some python experience but still muddling through. Rare pepe for troubles.

I don't think there is a library to do hex math directly in python. I think I need to define a hex converter, convert to int, do the sum, convert back.

That's cool, but it's not really what I'm after. The way I think this should be handled is with 16 lists, each containing the red, green and blue value. eg:
rgb0 = [21, 21, 21]
rgb1 = [32, 32, 32]
rgb2 = [48, 48, 48]

I want to find all possible combinations of adding the values in those lists one to each other at a time. I can do one on one with numpy:
import numpy as np
np.add(rgb0, rgb0)
np.add(rgb0, rgb1)
np.add(rgb0, rgb2)
np.add(rgb1, rgb1)
np.add(rgb1, rgb2)
np.add(rgb2, rgb2)

What I think I need now is some logic to do it in sequence. I know there will be duplicates but thankfully the total combination will be 256 which is the exact number of colours in a palette. Then just to output to file.

All done, it's fucking terrible work but it works.
