DocStr(wxColour,
"A colour is an object representing a combination of Red, Green, and
Blue (RGB) intensity values, and is used to determine drawing colours,
window colours, etc.  Valid RGB values are in the range 0 to 255.

In wxPython there are typemaps that will automatically convert from a
colour name, or from a '#RRGGBB' colour hex value string to a
wx.Colour object when calling C++ methods that expect a wxColour.
This means that the following are all equivallent::

    win.SetBackgroundColour(wxColour(0,0,255))
    win.SetBackgroundColour('BLUE')
    win.SetBackgroundColour('#0000FF')

Additional colour names and their coresponding values can be added
using `wx.ColourDatabase`.  Various system colours (as set in the
user's system preferences) can be retrieved with
`wx.SystemSettings.GetColour`.
