mColorDesigner

mColorDesigner is a screen color picker which displays color values in MUNSELL, RGB, HEX, HSB, XYZ, xyY, Lab, LCH, and CMYK formats.

Handy hot keys are provided to copy color values to clipboard easily. It shows color values in multiple color models/encodings at the same time. The program also has an ability to export "Favorite" colors to Adobe color swatch file formats (.ase & .aco).
