From the explanation

“Sure, you can see the 2D rectangle of colors, but can you see deeper? Counting color patches in the featured image , you might estimate that the most information that this 2D digital image can hold is about 60 (horizontal) x 50(vertical) x 256 (possible colors) = 768,000 bits.”
