Picture an apple in your mind. What colour is it?

...

Most people say red or green.

If you don't see a colour then you have aphantasia.

Wait, but, I know apples are red. I mean, picture "2 + 2 = " in your head and fill out the scene. What comes after the equals sign? It's 4, obviously. Nobody needs to hold anything in their visual field to know that.

Wouldn't a better test be one of "visual reasoning"? I'm thinking: construct a visual scene, object A is on top of object B, etc., and then ask a question that would be obvious to someone actually seeing the scene, but very difficult to reason out otherwise. Obviously such a test would be hard to come up with, hence why we don't seem to be able to talk about this stuff very well.

Yeah. I mentioned this elsewhere in this thread but the big thing that made me understand (some of) the gulf in terms of visual rendering abilities was murder mysteries. I read a lot of them with friends and oftentimes mysteries rely on an ability to construct an image of the scene in your head. Not being able to solve such a mystery doesn't mean you have aphantasia, of course, but there's this feeling for me in these that they're literally impossible, and yet other people can definitely solve them.

Without spoilers, could you just list one or two such murder mysteries for me to read both for enjoyment and as a bit of a self-test?
My memory is really bad for this kind of thing, sorry. I think some of Keigo Higashino's recent translated works have this kind of physicality in their mysteries, but I'd have to reread them to remember ahahaha. (But on the enjoyment angle, I do really like Higashino's works, so I do recommend them if you like mysteries)
