Adobe kulers

Adobe's "kuler" site is a place to get ideas for colour themes (sets of five colours) and/or explore the world of colour by creating your own combinations.

You need to set up an account in order to get the colour information to use in a web or other documents. Once you sign-in, you can also create and save your own themes. The themes can be downloaded as swatches for use in Adobe products.
