When we landscaped our backyard, I had asked for a mix of white and purple iris. I didn't specify equal amounts of white and purple (lesson learned), so when they finally started to bloom, they were basically all white. As any watercolorist knows, painting white is the absence of paint. So making a painting colorful or interesting with white flowers can be a challenge.
I had taken several pictures of some blooms in the garden from all different angles to compose this painting. Sometimes, I also fill a vase with flowers and just keep turning it to get different angles.
Today, I looked out our window to see the first iris in bloom. Low and behold, they're purple!
