I have never been great with the use of color in my photos. I started to read "Understanding Color in Photography" by Brian Peterson. One of the many exercies was to go out and take photos of one color. I found this hard to do creatively. I went out looking for the color red. I found plenty of red but not by itself and if I could capture it was a dull photo. I then decided to find photos of red with other complementary colors.
I went back and found some other colors in my photos,
