Colors Palette Generator turns a picture with a pleasing look into a palette of equally pleasing colours for your web site or design project. You can upload any PNG, GIF or JPEG that is less than 1MB in size and Colours Palette Generator will extract colours from it. The application creates three basic palettes of the light, medium, and dark colours, as well as a grid of 49 shades from the image if you're not satisfied with the palettes it has created. Once you've got the look you like, you can export it as either a Photoshop swatches file or as a CSS stylesheet. Free to use, no sign-up required.
