It seems one problem is that this doesn't work the way people seem to think it does.

I was able to achieve some response to a change by editing one of the color *names* to some other web-standard color name. But editing the hex code of the associated color doesn't do anything to that color. If you change the name of "Yellow" to "SkyBlue", then that square becomes Sky Blue in the drop down menu, and selecting it inserts "SkyBlue" tags in the editor, and the resulting text is colored SkyBlue. It doesn't matter that the hex code is still #FFFF00 (which is Yellow). Very puzzling and ultimately not achieving anything like I want.

I want to make the Yellow "less brite" - instead of #FFFF00, #FFFF66 (for example). There seems to be a bunch more to making that happen than just changing this code in the drop down menu.
