    Shadows do generally overrepresent the color blue due to rayleigh scattering.

    Brains are also very quick to make assumptions and also very rigid about keeping them. The spinning dancer illusion, even when you already know you can and have seen it spinning both ways, it can be difficult to switch percepts.

        Sometimes I can and sometimes I can’t. When I looked this up earlier, I was able to switch twice. But yeah, if I’m just staring at it, it’s basically impossible.

        I switched the first time because I looked at the reflection underneath the dancer, and that seemed to remove just enough visual context that I could reorient my perception.
