Last night in class I had to present a lesson plan (keep in mind, this is only my third week studying education. Clearly, we don't mess around). Mine was about the importance of color choice in art through the ages, the photos below are the examples I used to illustrate the key points. Then I transitioned into a new assignment of taking a classic landscape masterpiece and copying it, but using the complementary colors, which are opposite each other on the color wheel. I kindof want to do this project myself now.
