I found the idea that your eyes can automatically "flood fill" very interesting! I actually also see the left donut colored differently, as a very light purple. I'm guessing that this could be because the right donut clearly appears to be colored differently, which helps distinguish the object as a "donut," so my brain fills the left one in with a color to distinguish it from empty space.
