But for the purple label, color is inherited from a button (SquentialBtn) present in a different screen as shown in the above image.
Everything looks fine until we know the following fact, Power Apps renders all the controls and data of the screen currently in use. When we are inheriting color from other screen Power Apps will load all the controls in that screen also, which can lead to unnecessary performance degradation within the App. Also, one other very common scenario is that where form control in one screen is attached to a gallery control in a different screen. Try to avoid such scenarios if possible.
Best Practices: - We can declare global variables at the start of the app and use them anywhere in the App. With this trick only controls under screen getting used will be rendered, hence increasing the performance of the App. Below is the example for declaring a global variable.
