tkColorChooser is platform specific, on windows it actually uses
ColorChooser (check msdn for that) to display the color picker dialog.
On unix != macosx you will get a generic one which doesn't even have a
Even if you want to target only Windows, I don't think you can add a
hook (be it through pywin32, ctypes, ..) into windows' colorchooser to
load a custom palette. It is possible that there are better functions
for this in the windows api (which then could be suggested in the tk
bug tracker to replace or use if available instead of ColorChooser),
or maybe it is even possible to add a hook in ColorChooser somehow but
I don't know how offhand.
Now, the less hacky option is to create a widget yourself. tk comes
with a demo called tcolor which already supports rgb, cmy and hsb, so
all you have to do is put a "pallete bar" on it (and convert it to
python =) ) and have total control over it.
