Right now I find myself very drawn to explore colours and the effect on our mood or emotions. I like how different combinations create different vibes from a painting. For that reason I keep my motives very simple to give the color space and effect.
Like here: I used the complimentary colors violet and yellow, and deep red as a “frame” to make the painting energetic. My guy on the edge is adding some dynamical element while he is looking serence. But you can see he is up to something.
