I love what @Galen Gidman has done with http://brandcolors.net. I find myself going back to the site several times each week to grab swatches.
I decided to take the brands he listed there and create an Photoshop .aco file of all of the brand colors. Download the Full Set.
I also created a swatch set of the "Top Brands" if you don't want to load the whole set. Download the Top Brands Set.
Enjoy—and Follow me on Twitter!
