Here is a video with gpick in action:
Features:
- Fast color picking
- Magnified screen area
- Magnification from 2 to 10 times
- Colors automatically named
- Closest color name is found using CIE94 color difference function, which is closer to the way humans interpret color differences, than difference of red, green and blue color amounts
- Palette export function
- Inkscape/Gimp Palette (*.gpl)
- Adobe Swatch Exchange (*.ase)
- Alias/WaveFront Material (*.mtl)
- Picked colors can be copied to clipboard in multiple formats
- Hexadecimal notation - #rrggbb
- Functional RGB notation - rgb(red, green, blue)
- Functional HSL notation - hsl(hue, saturation, lightness)
- Custom conversions can be done, but requires some Lua language knowledge
- Oversampling with five falloff types
- Multiple pixel values are averaged to help picking colors from sources with noise, patterns and etc, where each pixel is different and overall color is produced by different amounts of particular color
- Mix two or more colors using variable number of steps and different mixing types
- Create lightness and/or saturation variations
- Create harmonious colors
