I really liked this picture because the two towels on top of each other provided both warm/cool color schemes as well as complimentary colors, and I thought it looked really good like that.
I took this picture outside where a store was selling flowers, and the yellow contrasting with the purple was really pretty in the sun. Also the little yellow bit in the middle of the purple flower made it even more contrasted.
This picture was one of my favorites because of the different shades of green that the grass had. The sun was really bright that morning, and the droplets of rain made the grass sparkly. This picture has really intense colors in it and I thought it was a good representation of bold/intense colors.
