function from a base 32 number to an RGB Color (0-255,0-255,0-255) tuple

33 Views Asked by At

I have long base 32 number. I would like to map a sub string of it into an RGB color which means a tuple of 3 0 - 255 numbers (Alpha is always 255 for me).

I wonder what is the best way to do so.

I am looking for a way that will be uni-formal and as unique as it gets. I will prefer it to use as less chars possible.

5 chars of base 32 gives us 32^5 = 33,554,432 which is much bigger than (0-255,0-255,0-255) = 256^3 = 1,6777,216 So I believe 5 chars is enough to do so.

I've tried using range normalization but that is not good because I get real numbers which is not useful when talking about RGB pixels (need to be integers).
