Limiting myself to just these 2 colors was quite an experiment, forcing me to use the paints to their fullest. I varied the intensity by using full strength pigment down to barely any pigment diluted with water. And I mixed the red and green pigment in varying proportions to get as much color variation as I could.
The range of tones amazed me, from the lightest light, to the darkest dark.I have read that it matters less what colors you choose, than the variation and patterns of light and dark that you create in your painting. Simplifying this concept in one challenging exercise helped me understand it. Getting outside of my comfort zone always seems to result in learning something new!
