This simple little painting was a lesson I taught about the color yellow. Yellow is the primary color that is between orange and green. Yellow is in the visible spectrum with a wavelength between 570 and 590 nanometers. Visible light falls between 400 and 700 nanometers which places yellow somewhat near the center of the visible light spectrum. It's a radiation that we all can live with and enjoy. Radiation isn't always a menace. It's radiation that allows us to see. Discussing yellow on the quantum level can be fun for physicist but not too much fun for artists like me. I would rather make my canvas explode with the radiation caused by a lemon and it's reflection in a pewter cup than to write a dissertation on it. So this painting is the culmination of my lesson with my students. We never discussed the wavelength of the color we were using. We just finished our paintings and then sat down and had some great tasting tea with lemon. visionary imagist "Joey"
