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

Hey Ben Cunningham,

thank you very much for your help. But matlab publishes the follwoing mistake:

Error: File: finallasttry.m Line: 1 Column: 20

Incorrect use of '=' operator. To assign a value to a variable, use '='. To compare values for equality, use

'=='.

What can I do that it works

Kind regards

Robin
