+"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`.
