[wxPython] wxColour equality testing?

Hi!

I've serious problem width testing two wxColour objects equality.
When I say:

from wxPython.wx import *

a = wxColour(0,255,0)
b = wxColour(0,255,0)

if a == b:
  print 'equal'

Prints nothing! That means that a and b are nonequivalent!?
Or cannot use this '==' operator to wxColour objects?

Thanks:
