When a client tells me their priority is to show tons of personality in their design, I get all excited because it means they don't want full fonts or colors! It's amazing how creative you can get with color combinations, and how much personality various combinations can add to a design. I've used the first two color combinations here and loved them. I really hope I get chance to try out the mustard and pink combo one day! (Use the color picker browser add-on to get the color codes.)
