Pointe-aux-Chenes wharf 2

If you're a photographer working with Photoshop or a buyer of those little expensive ink cartridges for your color printer, you'll say "cyan" rather than "aqua." They are two names for the same color.

"Aqua" is Latin for "water." The Spanish "agua" is obviously related. Therefore, it's quite an appropriate color for a wharf by the bayou.
