> I’m interested to see how these variables are handled. My inclination would be to program the notifications so they sense the background and adjust accordingly, but I don’t know enough about programming to know whether this is possible.

<p>A version of this problem is solved really well, especially on mobile. When you pay attention, you will notice that both iOS and Android detect the background and then make a determination if the home bar (the bar on the bottom of the screen to take you back to the home screen) must be "white-ish" or "black-ish" </p>

<p>For example: See the gesture bar in the bottom here - it's "dark" to highlight the contrast against the content background</p>

<p>Here's is the same gesture bar against a dark content and see how it's turned <em>lighter</em></p>

<p>This is done super efficiently while keeping 120fps in modern phones. Now, this is the case of "one" instance. The question is how is iOS planning to do this for <em>all</em> liquid glass elements at 120fps and what're the boundary parameters. </p>

<p>Apple really killed it by delivering on this. </p>
