I have looked into the tr function indeed, but thought that sed could do the same thing in this case. I just have a general concern about the use of regular expressions in the tr function, since "Most of the special RE codes do not apply in the tr function. ", so recognising hex color codes could be an issue.
UPDATE: Unless of course you mean that I first need to extract the hex color code, then pipe (|) it through to the tr function?
