Yes, absolutely... some people have no idea of color coordination. They may be brilliant when it comes to programming or whatever, but ask them to put together a color scheme that works, forget it :-) Most of them admit to it as wellBut is anyone really that bad with a sense of color? For every type of site, anyone could easily figure out a starting color, and then follow with shades, and blacks and grays. Whatever looks good with it really.
That's where these color schemers come into play....
Just my aussie 2 cents worth :-)
