The brightest colors one sees on the reef, here in the Caribbean, are the colors of the fish. Perhaps they're basically a little silvery under the reds and yellows, so they reflect more light? If you dive deep, a red sponge looks black, but a red fish still looks red. That's a Blue Head Wrass.
I need to go back here and see what's off in the distance, a whole two hundred feet beyond here. Not just a blue void! Snapper back there running away from me, believing I could have a speargun. Fish behave much differently in places where there's no spearing allowed.
Great Star coral down in front(not a plateful of olives). A wavy sponge, and three Mustard Hill corals beside the orange sponge. Oh, and a purple rope sponge on the left. And a few other animals. None of these thingies are plants, you know!
.I guess this photo is too complicated to use for a little painting, hey? LOL
But the dive shop still doen't have electricity after the hurricane, and my tanks are empty. Boo. Maybe I can find one to rent--- And I'm back online at home with my computer full of photos, so at least I can post some underwater images of some kind for you.
