Thanks, @kfrajer, most grateful! 😀

I didn’t know about the first hint, thanks for sharing it, as well as the links.

I mostly care about the `PShapes`; the spheres were used for illustration purposes. But I was interested to see if the spheres were affected by the surface’s colors.

Here’s a gif of the original with the new hint:

Here’s a gif where I make both surfaces red (though they don’t seem like the same color due to the [simultaneous contrast](https://www.colorduels.com/what-is-simultaneous-contrast/) of their frames:

Seems the spheres use a different shading strategy…

Thank you again! Life can now continue…

Adding a couple more pertinent links Kf’s links led to:

- [Program to test hint() with transparency](https://discourse.processing.org/t/program-to-test-hint-with-transparency/4361) (excellent forum post)
- [hint()](https://processing.org/reference/hint_.html) (processing ref doc)
