What do you see? I see an archipelago of small islands in a deep blue sea. I think there are rocky shores and shallow waters around the islands.
Or it simply could be blue paint peeling off an old metal door. You can see the metal surface is made up of crystals, or perhaps its a decorative feature on the metal doors surface.
Or it could be strange clouds on a distant blue planet. Looking down from above or up at an azure sky.
Imagination is fun.
