That isn't much context to work on. There are a number of "psychic 
debuggers" in this ng, but I'm not one of them.

No, it should be:

  self.colorselect = ColourSelect(self, -1, [0, 0, 110],
                     wxPoint(70, 200), wxDefaultSize)

(And you might as well lose the wxDefaultSize, as that's the default 
parameter in cases like this.[*] The -1 can be replaced by an explicit 
ID value, if the need ever arises.)

I'm amazed you see a memory leak warning, but no error message from 
Python itself. I often noticed memory leak warnings after a stack 
trace. This hardly ever crashes wxPython, but does seem to interfere 
with properly disposing some of the objects that have been created. 
Once you fix the error the leak will disappear.

No, It's actually just a wxButton type control, but the caption has 
been replaced by a colour.

Using sizers in dialogs is a bit more critical in dialogs than in 
normal wxFrames/Windows/Panels, though.
