It wasn't any more of a mental image than the color "olo" is.
But yeah, when I close my eyes and imagine an apple, it hangs out in the black void all bright red like that.
That's so bizarre to me. I can "picture" an apple, but I'm not literally seeing something resembling an apple in my mind. It's closer to the classic object-oriented example of "Apple isa Fruit", except not in text but in vague geometric shapes that to me say "appleness".
