One could interpret this week's challenge in several ways, but I chose to focus on the idea of "natural colour" to mean colour in nature. Since, except for cold blue winter skies, it takes a subtle eye to see colors in a northern state like Michigan during February, I turned my thoughts towards what I might find of the natural world inside my house. The abalone shell fish/bottle opener sitting on Ed's grandfather's desk caught my eye. I'd bought this art object from Pablo on a day trip to Mexico during last March's visit to my friends in San Diego, California. He'd told me how he would dive for the abalone, scrape its shell so the iridescence would come through, and then use it to create jewelry and other objects to sell to tourists. By the way, I was careful not to enhance the color of this photo using any of Photoshop's many tools. It is natural in every way...
