For comparison purposes: http://www.valdyas.org/~boud/colorpicker_ps.png.

The purpose of the big color picker is to select a particular color 
accurately. We should define working spaces for the color spaces show in the 
docker: that means that we need to add options for default profiles for 
hsv(?), rgb, lab and cmyk in our preferences dialog. The big color picker 
should have a gamut warning ico. Only hsv, rgb and lab should be selectable 
using the color field and slider; hsv, rgb, lab and cmyk should be settable 
numerically. It should be possible to easily find the nearest color from a 
given out-of-gamut color.

The big color picker should be a docker window that is not shown by default 
and when enabled floats by default until docked for the first time by the 
user, and it should be a dialog that pops up when the color button is 
(double?) clicked.

Yes -- so we should define a default profile for cmyk in our settings.

And this docker should have a history section. Something like: 
http://www.valdyas.org/~boud/hsvdocker.png would be great. But I guess that 
we cannot get that done before 2.0.

Yes. That could be either a docker on its own, like the palette docker, or a 
second tab to the hsv color picker.

Of course, all this doesn't mean that we don't need the paint mixer docker 
mixing green again before our release!
