I would strongly suggest you pick up a bunch of gel-maunfacturer sample packs. Bogen, Lee, Tiffen, they've all made them & they should be available in a good camera shop. Basically you get a big swatch book of a huge range of colors. Just rip out the ones you want to use and tape them over your flash head. Not only do you get a wider range of colors available, but you also can manipulate the power settings on your flash...something you definitely cannot do with the Colorsplash. And to top it all off, these swatchbooks are free. I've been using these things for nearly ten years now and they're fantastic.
