Adding either a colorized grid or horizontal lines causes the brain to see a grayscale image as a colored one. This is known as the Munker illusion.
@Mahaer_Mahmud the brain is a pretty magical device :)
@yogthos Really fascinating!
@yogthos waaaa holy shit
@yogthos does it not work for vertical lines?
@Sapphicgiraffic looks like it still works
@yogthos what? that's so cool!
I would like to see the original images to see whether my brain came up with the right colors.
@gattogateaux I imagine averaging out colors is probably a core part of the visual system. But could be an effect similar to color blindness for example.
