The seventh sessions of the Trihue Watercolor class for Winter 2018 were held on Wednesday, February 28 and Sunday, March 18. The colored light studies were critiqued. The new topic, surface, was introduced. Surface has to do with light being reflected or absorbed. Similar to the value scale of white to black, you can imagine a surface scale from very reflective to not at all reflective: mirror to black velvet. Still water at a distance will reflect the sky or other surroundings, acting like a mirror, while looking down into it at a steep angle, or where an object is between us and the light source, you can see through it like a window. The new painting assignment provides a chance to tackle this intriguing phenomenon.
