Details:

Octave and Matlab differ in default settings for the backgroundcolor,
foregroundcolor and value properties of uicontrols. Here is what Matlab does
and a file is attached of a screenshot illustrating the differences:


>> F = figure;
set(0,'defaultuicontrolunits','normalized') ;
u(1) = uicontrol(F,'Style','checkbox', 'String','string', 'Position',[0.3 0.8
0.4 0.09]);
u(2) = uicontrol(F,'Style','edit', 'String','string', 'Position',[0.3 0.7 0.4
0.09]);
u(3) = uicontrol(F,'Style','listbox', 'String','string', 'Position',[0.3 0.6
0.4 0.09]);
u(4) = uicontrol(F,'Style','popupmenu', 'String','string', 'Position',[0.3 0.5
0.4 0.09]);
u(5) = uicontrol(F,'Style','pushbutton', 'String','string', 'Position',[0.3
0.4 0.4 0.09]);
u(6) = uicontrol(F,'Style','radiobutton', 'String','string', 'Position',[0.3
0.3 0.4 0.09]);
u(7) = uicontrol(F,'Style','text', 'String','string', 'Position',[0.3 0.2 0.4
0.09]);
u(8) = uicontrol(F,'Style','togglebutton', 'String','string', 'Position',[0.3
0.1 0.4 0.09]);
>> get(F,'color')

ans =

    0.9400    0.9400    0.9400

>> cell2mat(get(u,'backgroundcolor'))

ans =

    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400
    0.9400    0.9400    0.9400

>> cell2mat(get(u,'foregroundcolor'))

ans =

     0     0     0
     0     0     0
     0     0     0
     0     0     0
     0     0     0
     0     0     0
     0     0     0
     0     0     0

>> cell2mat(get(u,'value'))

ans =

     0
     0
     1
     1
     0
     0
     0
     0



In Octave, backgroundcolor is set to [0.83922   0.82353   0.81569],
foregroundcolor is set to [0.13333   0.12157   0.11765] and value is always 1.
Default color for a figure is [1 1 1].

My take on this is:
* while it might not be necessary that Octave and Matlab have the same default
values for colors, it would be great if figure's color and uicontrol's
backgroundcolor match.
* default setting for the value property in uicontrols should match Matlab's.
* there is an issue with checkbox, popupmenu and radiobutton uicontrols where
it is impossible to change the backgroundcolor property (try with
set(u,'backgroundcolor',[1 0 0]) )
* there seems to be an issue with a popupmenu uicontrol where it is impossible
to change the foregroundcolor property (try with set(u,'foregroundcolor',[0 1
0]) )
