No longer colour blind
Here is something very cool. If you are a designer creating a unique brand language for your clients you will love this tool available free from Adobe. It's called Kuler and, quite frankly, I have never seen a web application that is cooler.
Here's how it works. Log on and create a colour theme with the flash generated tool box, manipluate the palette of 5 colours using 7 variable settings: Analogous, Monochromatic, Triad, Complementary, Compound, Shades and Custom. Modify using sliders if you like. You can also extract the RGB, CMYK and HEX numbers to translate to other programmes like Quark or Photoshop. Save your creations and share them with other users. Check the creations of other users, rate them. It's useful and great fun.
I am not much chop with colour, so I love this!
