I'm a bit behind on getting on board with the flash of red so thought I would do it today then realised I had to have red in it!
Thanks photoshop for providing a red sea. I hope this fits the bill:)
Wow. We have a phenomena that happens on our coasts sometimes called "red tide". It's an algae bloom. Though I've never seen it in person, this would be an interpretation of the name. This is really an eerie photo, but well done.
