For the Ragtag Daily Prompt: jet.
I am going to use the meaning of the color jet: jet black. The color is from jet, lignite used in jewelry. Lignite is a precurser to coal. I have a necklace of jet beads from my great aunt.
This coot is jet black in the sun and against the water. Coots look self-contained to me, shyer than the ducks. They look down in the water and make noises to them selves, not like the insistent mallards. They move a little bit robotically. The neurological wiring seems more primitive than the ducks.
