Aphantasia doesn't lack color, it lacks a place to put the color and therefore color has no relevance other than descriptive. The ball is just an imaginary object, like an uninitialized variable. I can imagine that one exists, I can imagine that it would have traits like red or blue, big or small, bouncy or not, but I don't visualize it, and those fields need to be filled in one-by-one, they aren't defaulted when I imagine a ball, and nothing changes other than the description if I change them. A ball rolling off a table is more like the lead into a physics question to me than an exercise in imagination.

As someone who has been coding for 45 years, this is absolutely the best analogy describing aphantasia I've ever read. Obviously, it works only when talking to another coder, but that is better than nothing.
