       dc.SetLogicalFunction(wx.XOR)


means that colors are bitwise XOR'd with the background color. It looks 
like you may have borrowed this from my (or someone else's) rubber band 
box code. It's there so that you can draw a visible line over any other 
color. If you always draw red, you won't be able to see it if the 
background is red.

However, if you do want that, get rid of that line.
