Hi, I use an intel iMac loaded. What I am looking for is an application (free/shareware) that will allow me to apply colors that are vibrant (something the apple colorwheel just doesn't have), things like glittering gold or silver or polished aluminum and Neon... you get the idea. I would optimally like to be able to create something in vibrant color then use a program like 'Image Tricks' or 'Seashore' to alter or add layers
