I mean a simple button that dumps alternative hex values into the fields. Could be one button that sets the fields to your new default values, and one that fills in values for higher contrast. I could have worked out any old (or good new) values on my own, but there might be many users who don't really know what "ABCDEF" means... :-) For strange reasons, the color popup refuses to work with iCab - I'm not sure why, but I will check it. However, there are people without JavaScript as well, and then the hex values might be a bit of a challenge for some...
