Mixing up warm and cool strings of greens for my limes.
My plan is to experiment more with broken color, so I have attempted arranged the strings so that adjacent colors have the same value. The warm string uses Sap Green and Cadmium Yellow Light. The cool string is based on Viridian and Cadmium Yellow Light, with a bit of French Ultramarine added to the darkest step.
This black and white photo shows that I was able to match the values pretty well in most of the steps, although the three steps above the darkest level could use some work.
