This blue, pictured on the pinky below, is the most beautiful, deep dark blue you can find. It's what you imagine the deepest ocean color would look like. I have it paired with White Wash, Antarctic Sea Ice, North Sea Swells and Atlantic Surf.

Beautiful blue! North Sea Swells shown on thumb.

Also showed in order from thumb to pinky:
North Sea Swells, Stormy Pacific, Atlantic Surf, Antarctic Sea Ice & White Wash.
