Is this shot by doug.deep even from this world? Well...it's from the undersea world.

Although it looks like a test for colorblindness, this brilliant, unusual, colorful image is actually a starfish -- an Asterodiscides truncatus, to be exact -- found at Sydney's Shark Point, Clovelly, at depth of around 55 feet. I love the amazing texture this image reveals, and the colors simply pop. Considering how infrequently we get bright, bold red images out of underwater shots, I have to rate this image as a favorite.

If you have any underwater shots that look like colorblindness tests, Rorschach tests, or any other kinds of tests, please add them to Divester's Flickr pool and amaze us. If your shots only look like fish, you can still add those to the pool, too.
