It was on a whim that I decided to paint this subject on a watercolor paper treated with Gesso. But I wish I had not. The color shine on gesso, so this method looks so inviting. But on gesso, I wrongly estimate the amount of pigment on the brush. Gesso does not absorb the pigment very well, so it stays on the surface and does not blend well. I am not going to be tempted again.
