The color red immediately comes to mind when I hear blood. That thick bright red stuff inside you keeping you alive! I would argue that this piece is analogous. After analyzing the color wheel looking for something to call this, I noticed that there was a similarity to an analogous color palette. It is organized as different tints of orange, red-orange, and green. The orange is a shift in tint on the outer layers of the image. The red is a shift in shade and tint.
The first thing that comes to mind when I hear vineyard is green. I think o The three colors at work here are purple, green, and brown. This is triadic. The brown is a darker shade of orange, probably near the border of black. The greens a variety of shades and tints. The purple is a a darker shade of it.
