Tidewater

I have been setting up the gallery, cleaning the studio, and painting the background for a mural. That's where the "tidewater" comes from. Have you ever wondered how names are picked for colors? Like what does "tidewater" look like. What would be your guess? Unfortunately I can't show you; I don't have a way to scan the color in to the computer. I used it for the sky; starting at the horizon I made it as light as I possibly could and deepened it as I went higher on the wall and ceiling. What should I add to my landscape? Any suggestions?
