Yellow is the Night

I started this painting at 6:15 PM. I painted and painted and then it got dark. When it got dark I figured I got this far so I just kept on painting. As it got darker I used more muted darker color in contrast with just yellow and white. I learned that night time with street lights can pretty much be achieved with black and yellow and slight variations of these two colors. I painted until 9:30. It got so dark I could not see my pallet. But I knew where the yellow ws and I knew where my black was. So I just painted with those colors and White. These colors mixed with the colors that I painted when it was light. People walking by were amused to see an artist painting in the dark. Nice evening to paint.
