Heh. Personal anecdote: at 10 seconds I would do as you expect, but if the gap were longer I would do much better with sound. I discovered relatively recently that I simply cannot remember colors. My vision is fine, and my short-term memory for colors is also fine. If I'm in a room and you ask me to close my eyes and say what color the walls are, I can do it. But if you ask me the color of the wall of my bedroom, where I go every night, then I will only be able to tell you if we recently painted it and verbally discussed paint colors. (I think it's a shade of blue? Or maybe green. Possibly gray. My family likes to pester me with this question, so you'd think I would memorize the answer at some point, but I haven't.) I'm kind of curious how common this is. But since I lived several decades without noticing it in myself, I wouldn't be surprised if it wasn't very well recognized.
