You still haven't answered the most basic questions as to the criteria:
1. How does the code determine what letters to colour; and
2. What colour to make them.
Telling me they colours have RGB values (as all do) doesn't tell me what determines when a particular colour is to be used.

Re 1, for example, your first post seems to suggest the words all start with a particular letter sequence (abc). If you want the be able to specify the staring sequence, fine, but you need to say so. I don't want to waste my time coding for 'abc' when it isn't that at all and could be any number of different strings.

Re 2, for example, your first post suggests the colours may be linked to whatever the words end with. If so, you need to say so. It's no good me guessing.
