Adobe has announced three Photoshop Touch apps — Adobe Color Lava, Adobe Eazel and Adobe Nav — for the iPad.

Adobe Color Lava (US$2.99) allows you to use your fingertips to mix colors on the iPad, creating custom color swatches and themes to transfer back into Photoshop. Adobe Eazel ($4.99) takes advantage of cutting-edge painting technology by letting digital artists create realistic paintings with their fingertips, and introduces a new kind of interaction between “wet” and “dry” paints. These paintings can then be sent directly to Photoshop CS5 for compositing or for taking the artwork further.

Adobe Nav ($1.99) lets users select and control Photoshop tools using the iPad as the input surface, customize the toolbar, browse and zoom in on up to 200 open Photoshop files, or create new files. All three apps are available at the he Apple App Store (http://www.itunes.com/appstore/).
