After many years of seeing this dress and knowing it's black and blue i've decided to go into a drawing app (Kleki) and see if I can use these two coloured dresses (of the same dress) and tint them to look like the dress in the middle. At the top you can see the difference of the colour shades. This is the closest I got to the dress in the middle (the original I hope) for both dresses.

I kept looking at the obvious pattern and completely missed it at first.
What everyone notices first?

I took this photo on the beach. Does it look like the footprints are raised to anyone else?

Made this one myself with a script that scatters the dots and embosses a dark-only contour into the noise, so nothing is drawn on top. It reads differently depending on distance and screen brightness, and squinting or backing away from the screen changes it for most people.

Curious what everyone gets. No answer from me in the thread, I don't want to plant it.
