I painted one using the same technique I picked up from artist Julie Karlsson, using Black Mars Watercolor Ground over 9″ by 12″ Cold Pressed Paper. The second was done based on a photo of a baby polar bear waving hello and his mom trying to sleep a little.
Last week, I read an ad from Daniel Smith about an artist named Julie Karlsson who was promoting the use of Daniel Smith watercolor paints and watercolor ground. I have used watercolor ground but not a dark color. I ordered Mars Black but it did not arrive yet so I used white ground and dark blue as a background. Then I used several watercolor and gouache paints to come up with this scene of dolphins swimming at night.
