From Smart Is On:
Easy Color Themes is a complete tool for visual color design, intended for Designers, Webmasters, Painter Artists, software developers and anybody else that works with a color palette. You can grab colors from you screen, using a color picker with optional zoom, that automatically gets out of the way, so you don't have to move it to grab a color below it. You can create your own color list, specify custom color names and also export your color themes to BMP. Additional features include screen capture, project support, zoom and multiple color output formats (Visual Basic, Visual C++, HTML and custom).
