After a cursory search, I found this article, where the author presents basically the same equation: blog.demofox.org/2019/12/07/b...
Only here, they've replaced the combinations of coefficients with subscripted constants like you might expect of values that you're supposed to plug in yourself.

Worth noting that the picture and accompanying desc. were written by one guy in 2003, with no edits since other than for formatting. At one point, this is what the entire page for Bezier Triangle looked like. I think this is a case of bad notation, and possibly a not necessarily correct equation.

I think of KH3 as a good example of a game with a lot of clutter but doesn't use specifically yellow paint to draw your eyes to where you're supposed to go, they just use subtler techniques that were already being used in the industry. Chests *are* yellow, but don't look haphazardly painted yellow

Ahh, so many better pictures I could have chosen...

I wish Minnie and Stripey the best, and I reciprocate with Cinnamon and Ginger.
