Depending on your brain you will see different things! This experiment relates to visual cognition. If you see a dark orange circle your brain leans high-level vision and the dimmer the orange circle is (or if you don’t see one at all) the more you lean low-level vision.

What if I can alternate between both?

Edit: I've looked at it a bit more:

I can make the black circles into "windows" that show a red circle behind a white wall.
I can also overlay the red circle as a mask in front of the black parts, so that only the black parts make the red circle visible (like in a shader program or when masking parts of an image in a photo editor).
Then I can also envision a red hue along the white parts of the image that follows the silhouette of the red circle.
And then I can "deactivate" the silhouette again, so that the red parts are simply drawn on top of the black circles, with no relation to each other.

I think this is just a test to see if you have experienced a certain effect before.
