Symphony.

I have some site where the client can select predetermined colours from a drop down field, the are generated as css in the header of each page. I would like him to be able to use any colour, besides letting him surf to an external color picker webapp, and paste the hex value in a field, what aother way can I solve this. What about a color picker extension, in line with the calendar extension.

PS still no way of getting the backend-applied css in an external file?....
