I am writing an application for astronomical use, and a "Night Vision" 
feature is sometimes required. I.e. when you use the PC in total darkness, 
you want the application to have red panels RGB =(128,0,0), and otherwise 
white text fields should be even darker RGB =(64,0,0). The point is that a 
PC screen in the dark destroys the dark adaption of the human eye if you 
don't do it.

I tried using SetBackgroundColour(...) but it only affects part of the 
application. Dialogs are for example not affected unless it is set using 
explicit calls to that object. It looks like I would have to make many 
explicit calls to lots of different controls to switch to and from a night 
vision colour scheme.

Is there some way a global colour scheme like I describe can be set (using 
wxWidgets) so all panels, toolbars, menu bars, status bars get one colour, 
while text controls, check boxes, radio boxes, list boxes that typically 
have white background get another? This should be such that the colour 
scheme coiul be changed back and forth while running the program.
