Here is something interesting, and a bit strange.
PNG is a lossless compression format.
A 500px by 500px PNG RGB/8 image, all white will take up 4,815 bytes. The same image, but all black will take up 3,446 bytes.
This is as saved by MSPaint, not Photoshop.
Funny thing is, the larger file takes up two 4 KB disk sectors while the smaller file takes up one. So you can store twice as many black ones as white ones on a given drive, even though they are essentially the same image.
Just kinda weird.
