    You can literally sample the rgb values

    It doesn’t matter. This phenomenon can be explained by something called color constancy.

    I remember some versions of this image where I could literally switch between perceptions at will, when I imagined different surrounding light temperatures/environments.

    It’s a subjective perception.

      I can literally switch between perceptions with this exact image. It’s sort of like that “are there six cubes or ten” illusion. Depending on how I look at it, I can see either one.

        Exactly. Or that silhouette of a spinning ballerina. I can switch the direction that she is spinning at will as well. There’s nothing to go by because it’s a perfectly flat, projected silhouette without any shadows, so anybody is free to interpret the rotation however they like. 😁
