Each button has a property 'Background Colour'. You can use a simple state machine to set the colour in [Red, Green, Blue].
See the below code:
properties (Access = private)
ButtonState = 1; % Current Button State
end
% Callbacks that handle component events
methods (Access = private)
% Value changed function: Button
function ButtonValueChanged(app, event)
value = app.Button.Value;
switch app.ButtonState
case 1
app.Button.BackgroundColor = [1.00,0.00,0.00];
app.ButtonState = 2;
case 2
app.Button.BackgroundColor = [0.00,1.00,0.00];
app.ButtonState = 3;
case 3
app.Button.BackgroundColor = [0.00,0.00,1.00];
app.ButtonState = 1;
end
end
end
