The proposed changes to tk_chooseColor are the following:
- The resizing of window is locked (supposedly the resizing makes no sense, at least in the current version of tk_chooseColor).
- The default sizes of Tcl/Tk color picker are changed a little for more usability.
- The 'Move all' checkbox is added allowing to move all (R, G, B) selectors simultaneously.
- The 'Tone moves' checkbox is added allowing to implement the toning feature for a current color.
- The RGBCMY and their tones are added, in separate color boxes.
- The -moveall (0 by defauls) and -tonemoves (1 by default) options are added.
- The chooser is themed now. The themed choosers of font and color are shown beside on the above screenshot.
- A stand-alone Tk color chooser is available (see its screenshot above). Invoked with: tclsh tkclr.tcl.
