% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

Best Answer

function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
colors = [ 1 0 0; 0 1 0; 0 0 1]  %this will be your array of colors
if hObject.UserData == size(colors,1)
    hObject.UserData = 0 %if it reaches the end, reset
end
hObject.UserData = hObject.UserData + 1; %stores this data within the button itself
state = hObject.UserData;
hObject.BackgroundColor = colors(state,:);
%note: ForegroundColor is the color of the string, BackgroundColor is the color of the button
make sure you set the 'UserData property of your button to 0 for its initial state, example :
button = uicontrol('style','pushbutton',...
    'callback',@pushbutton1_Callback,...
    'UserData',0)
In this example, button will turn from red, green, blue, then the cycle repeats.
Can you be clear as to what you mean by 'saves its state?'
