Nice script, however...
Suggestions:
- I think you should have 'First Colour', 'Second Colour' and 'Third Colour' instead of 'Start Colour', 'Middle Colour' and 'End Colour'.
- If you select '2 Colours', the 3rd should be greyed out, etc.
- An error message should pop-up if you don't choose the appropriate colours.
- If you select '2 Colours' but only choose 1, you get no error and your text appears with wrong codes.
- An option to disable the script, without having to go into Scripts Preferences (for an example, see
CookieRevised's scripts.)
