function ChangeColorButtonPushed(app.PushButton) %app.PushButton came from another function
%cahnge background color
app.PushButton.BackgroundColor = 'red';
%continue to callback function

As long as your function has 'app' as a varargin you should be able to access your button handle.
For exemple if you want to know the coor of the button through a function:
function result=ColorButtonPushed(app)
result= app.PushButton.BackgroundColor
In general, "app" should always be an input of your funcitons in app designer
