It's easy to navigate, simple, and to the point. They have a section about Le Cuir with 5 or 6 palettes that they tossed out there for Spring 2011 (with great titles, like Enchanted Picnic). Some are typical spring with bright, light pastel colors and some are more for the summer, but one struck my eye (image copyrighted to Le Cuir):
