Watercolors are the essence of correspondence because of their transparency and the range in dry and wet.
My favorites are the Primatek Colors from Daniel Smith. They are mineral-based and pigment-rich. https://danielsmith.com/product/daniel-smith-primatek-watercolors/
I store information about them in a sketchbook. I enter them with heavy and light pigment. Water is an ongoing source of correspondence with watercolor: high pigment and low pigment mixes.

When I start a painting that will be a long commitment, I select colors and set up a correspondence chart to help me see how the colors work together. This system allows me to see every corresponding combination of colors 1:1 at high, medium, and low pigment density.

As the painting develops, I use this chart to build layers of color. I use very small brushes. This painting was commissioned during COVID-19.
