The left heart appears to be whitish whereas the right one blackish, though they are the same stripes of black and white.pic.twitter.com/A781ceGtWO
That's not true. The heart shape is made from white pixels in the left image and black pixels in the right
in both images, the heart is made of alternating stripes of white and black. if you were to replace the background in both with purple, the hearts would appear to have the same lightness.
Are you saying replace the solid white/black stripes with purple stripes? If that exposes an illusion, great - show that. As it is, this isn't an illusion cuz the hearts actually are different.
both hearts are made of alternating black and white stripes, and as such are not different in overall luminance.
the illusion is caused by the gray background around the hearts, which is darker on the left image and brighter on the right image.
The gray background is indeed lighter in the right image, but the actual meat of the heart is different, too - it's 255 white in the left, and 0 black on the right. I don't understand the illusion.
the meat of the heart is alternating 0/255 in one and 255/0 in the other.
How about this?pic.twitter.com/NkuncUcpWL
same overall effect, but since hearts are white/black in both cases (there's no black/white) less room for misunderstanding
