no,
this tool will work for krita, karbon and maybe other office apps.
if you just need the colour picker (pipette), you can use kcolorchooser. there will also be drag’n'drop for colours.

Are you going to make this a stand alone app so that the eyedropper can be used to find color values for use with other applications, not just krita or is there already something like that? I think there is and it’s for Gnome.

@ben
it is probably a bad screenshot, but the second colour chooser is not mirrored. the bottom side gets lighter, if a brighter colour is selected. if i have time in the end of summer, i will maybe try to make it better. there are also some ideas on the mypaint wiki (http://wiki.mypaint.info/Brainstorming/UI/ColorSelector#Color-changer_modifications).
the idea is to provide shades, so that an artist can see and choose colours, which he maybe haven’t thought of.

i will look into the anti aliasing thing, but it won’t be that easy as setting just one flag.

The Inkscape color-bar looks cool to me. I’ll maybe try to create a similar docker/widget, but that’s rather a bonus for the end of summer also.
Mixing colours is in the plans for krita 2.3 (afaik), some parts of it are already implemented. you can look for details here [ http://wiki.koffice.org/index.php?title=Krita/Painterly_stuff ].

thanks a lot for the comments..

Have you considered using something like Inkscape’s color-bar (don’t know if that’s really its name or not)? The bar along the bottom of the image which holds the colors of the current palette for quick selectional. The only question I would have is whether or not that would be a good use of space, though if it were optional it could be nice.

Moreover, a proper color-mixing scheme, on the picture, and maybe on a separate dock (i.e. an actual palette replica), would allow you to mimic the painting technique of using a limited set of colors and letting them mix to create the appearance of many colors, while keeping the image coherent.

Perhaps someone will be able to glean some useful information/insight from that… even if it did get a bit long-ish.

Adam probably meant the aliased edges of the pie pieces in the “new style” selector. That should be easily fixable by setting a QPainter flag.

Looks awesome! The “commonly used colours” sounds very, very useful (do any other apps have this yet?).

Given that it’s not even halfway yet, we’ll be expecting something doubly amazing by the end!

btw, I think Rsh was requesting anti aliasing on the edges of the shapes drawn in the colour selector. That would be my guess anyway.

Nice work! /me runs to recompile trunk

To be honest, I do not understand the idea behind the second color choser. It seems to waste lots of space by being mostly mirrored on the Y-Axis. But then, its not completely mirrored. Many colors even seem to be present multiple times.

Is this a placeholder for something else?

I’m unsure, what you mean. This is of course work in progress and I’m not done yet.

I am sure it took quite some work but leaving literal rough edges will not make a great impression! Good work though!
