We have a lot of good color resources online, like Colourlovers, however sometimes we need to come up with a custom and unique color palette using an old photo we took or an image found online.
Usually I use Photoshop to do that, applying some adjustments and filters to reduce the number of colors, getting the most visible ones. I tried some palette generators before but none of them caught my interest. But I may change my mind, Big Huge Labs Palette Generator does exactly that, automatically create a color palette from a photo, it's very nice despite the number of adSenses on the page, and it works faster than the others. Besides that it has some other cool features such as interaction with Flickr.
Choose or upload a photo and a palette of colors based on the colors in the photo will be generated automatically. Use it to help with art projects, website design, or even with decorating your home.
It's a very useful tool and definitely worth checking it out.
