i first saw this website when someone on the bus was using it & i kept staring at the pallet change as he moved his fingers across the mouse touch pad. last week i stumbled on it again on the how blog. kuler was created by adobe labs to allow it's users to create color schemes, view others & download the swatches for adobe creative suite.
the interface is really user friendly & aesthetically appealing. you can also search & create pallets many different ways. you can search by keyword, most popular or newest & create by analogous, monochromatic, triad, complementary, compound, shades or custom.
i'm using it to find color combos for the new apartment.
