It occurred to me that there might be a body mind connection involved when we watercolor. We might be able to utilize this connection to cool ourselves down during this hot spell.
Do me a favor and experiment on yourselves today. Select some cool colors from your paint box (think blues, lavenders, greys or anything that reminds you of the ocean.). I have no idea if the subject you paint will effect your body temperature or make you feel cooler. Report your finds to me as soon as you complete your research (painting).
