Not a good example, IMO. A triangle is defined as 3 points with 3 lines connecting each consecutive point. A better example would be: think of Tony the Tiger, now what colors are his skin, stripes, and bandana? But that's also not perfect because people are along a spectrum in the amount of detail they're able to see.

Weird. If asked to visualize a triangle, I see the "glowing lines in a black space." If I try to visualize a red/green/blue triangle, I can only briefly maintain the image before it fades away into the default white outline in the void.

However, when asked to think of Tony the Tiger and his stripes, not only do I perceive orange fur and red bandana, but I'm struck by just how freaking blue his nose is and it is uncomfortably persistent.

I can't see Tony's skin since it's covered by fur unless you count the "toe beans" and nose
