Eyedropper is a color selection and conversion utility designed for users who need to work with several color representations. It allows colors to be sampled from the screen, entered manually, or examined in formats used in graphic design, web development, and color analysis.
Unlike basic color pickers that display only hexadecimal and RGB values, Eyedropper supports a much wider collection of color spaces. A selected color can be viewed in perceptual, device-oriented, and mathematical representations, making it useful when comparing colors or preparing values for different applications.
The interface allows users to choose which representations appear and arrange them in a preferred order. It also includes a shade generator for producing related colors from an existing selection. Color names can be matched against established collections, including web colors, GNOME palette names, and the xkcd color survey.
This is free and open source software.
