When I think of a black and white apple in the context you described, vs. a red or green one, there's a difference. The way you've explained it makes me feel like we're similar, and I'm definitely putting too much emphasis on visual.

My sister, though, said when she thinks of something in her mind it's "blurry like [she doesn't] have glasses on", which sounds highly visual.

I'm wondering if it's more about semantics and a tomato/tomato like thing -- technically anything we visualize is calling up a memory, or at made up of various components from memory.
