Symbols question

[Brumsew]

Am 1/2 way through a large project with over 100 colours. For future reference, can I change the symbols used to letters?? The symbols on my current pattern are so alike they are almost impossible to discern one from the other.

I assume you are talking about the English alphabet. Can you guide me how to encode 100 colors in just 26 characters?

Using Unicode characters for your mapping in addition to ASCII.

The symbols are already mapped to Unicode characters.
