Does anyone know of a Free Software alternative for something like Adobe Color CC (previously “Kuler”)?

If not - anyone interested in possibly building one? I’m looking at you, @Jonas_Wagner ;).
It would be awesome to have a tool like this available to us (and other designers/artists would be interested, I’m sure).
No, but I really hate such links where I have to hit the back button like a maniac to go back to pixls.us!
If U don’t mind online this not bad, mono, complemetary (adjadcent/analogous, triad) and tetrad, plus randomize and some tools, many export options. I agree such a tool is usefull

PD
There are options for the 1% too XD
Not quite the same: https://www.kde.org/applications/graphics/kcoloredit/?edit
Why would you need an alternative for that? It seems to work fine for me, and it stealing my colors is not really of concern (at least to me) either so it would seem fine to just use that if it works. If anything it could be nice to have this built into an editor like gimp to quickly generate a palette.
