Inspired by Carina's Colour play post I've been tinkering with this online colour palette generator. You provide a link to an image online (I used my own that I keep on Flickr, but you could link to any image you like online) and the website analyses the colours in the image and spits out two palettes, one dull and one vibrant. It's designed for website building, but it's a fun tool for matching colours to photos for scrapbooking.
Below are my test photos with the palettes they generated - some are quite obvious, but others aren't what I expected.
