This is a library of user created presets for Apple's software Color. From coloruser.net. The presets listed here are stored in the .colorgrade format. It's a community of color accolytes so as well as allowing you to download for free, they also want you to upload your own color presets. You can recreate the 'magic hour', get that greenish Kodak 400 look or go for Film Noir. Lots of Canon 5d Mark II Presets available.
