Easier way to change theme color

Long-pressing the Niagara button just allows you to modify the tap and swipe actions. And we can’t modify the long press actions. At the very least, we should be able to change the appearance of the Niagara button (the theme color) by long pressing it. When we try to change an individual app icon, we get a pop-up window that shows similar app icon recommendations. Just like that, we could also get theme color recommendations in a similar window when we long-press the Niagara button icon. Right when we press the Niagara button icon after long-pressing the button, nothing shows up. You guys could literally link it with the current theme color option so that when we press the icon, the theme color window appears.

Sorry for the long-ass text. I hope I was able to explain things properly.
