Hi Day Hong Kim,

To change the background color of a push button, you can adjust the 'BackgroundColor' property. If you intend to change the color when the button is pressed, particularly for a 'uibutton', you can utilize the 'ButtonPushedFcn' callback function.

Below is a sample code that illustrates that:

function changeButtonColor
    hFig = uifigure('Name', 'Button Color Change');
    hButton = uibutton(hFig, 'Text', 'Press Here', ...
                       'ButtonPushedFcn', @(btn,event) buttonCallback(btn));

    function buttonCallback(btn)
        btn.BackgroundColor = [1, 0, 0]; % Change to red
        pause(0.1); % Pause for 0.1 seconds
        btn.BackgroundColor = [0.94, 0.94, 0.94]; % Revert to default color
    end
end

For more details, refer to the following MathWorks docmentation:

1. uibutton - https://mathworks.com/help/matlab/ref/uibutton.html
2. Creating callback functions - https://mathworks.com/help/matlab/creating_guis/write-callbacks-for-apps-created-programmatically.html

Hope this helps!
