Hi there bookgeek552,
Most everything by Bumble & bumble is good for color treated hair. Their is a new line one out called Color Minded. Besides the packaging being cute (I am such a sucker for that stuff) it is supposed to be a good UV protectant. You could mix and match the line for your hair type and use the UV serum as a last step.
Another great buy would be the Phyto Color Protect Radiance Collection Kit. It has everything you would need-shampoo, conditioner, and mask. I love Phyto because it is all natural and doesn't have a bunch of silcones to coat your hair--it actually keeps it healthy.
