There's no way I'm going to compute in my head "Well this gradient with three colors is going to look like this after I mix it on top of these 3 bottom gradients each with different colors, oh and an image underneath"
Clicking a button beats computing an image in my head in terms of mental energy cost.
Speaking of energy, a physical dial, or scroll control, would be nice to cycle through quickly.
Edit: I do really admire this author's technical deep dives though, very beautifully made
I mean, I didn't calculate what I wanted, but I built a mental model of what each mode does and when to choose which later.
