Adobe has a free web based colour tool called Kuler.
You can use it to create colour schemes, share them if you choose and store them if you want.
You can use a colour wheel to create colour schemes. In this case I have used a compound scheme.
The other way to find colour schemes is from a photograph. You can upload an image as I did, or you can use flickr photos.
There is a community areas and you can browse the colour themes they have shared for inspiration. Kuler is well worth exploring as I think many readers will find it useful and fun.
Adobe has also produced this informative video tutorial about Kuler
