Watercolor allows pigment to move as the medium dries; therefore, color mixing results in surprises as the material settles. Each color operates a little differently depending on the mineral nature of the pigment in the paint and amount of water. Some pigments are physically lighter and float to the top, while others sink, mapping paths as they dry.
Through making the river stones paintings, unplanned color relationships are unearthed. Small landscapes appear in each exploration. Edges vary with each "stone." Similarly varied are the visual weights of each one, relating to value, saturation, and type of pigment used.
Each composition focuses on the relationships between the stones, considering variety in size, value, and color. These relationships become the subject matter for the work.
Finally, it's beautiful to me that the sediment in the paint can create imagery related to the mineral that makes the pigment.
