There is a great chance that some of you were also annoyed of Windows miserable system color dialog. Especially if you are doing graphics stuff you might have prayed for a better replacement or that MS will fix that thing.
Yesterday i stumbled upon the Jovian Color Picker
at one of my favourite 3d forums. There was only one thing that was not working perfect which fixed author Ken Nign meanwhile (!) that i purchased it after checking the trial for a few hours. Give it a try if you need also a better color picker that can load and save palettes, supports a library of colors, can pick from screen or image, supports RGB, HSB, Kelvin, wavelength and web colors.
