One of the first things I have done in almost every painting class I have taken is paint a color chart or a color wheel. I never gave much thought to that in my current practice, but then yesterday I was painting this chart after acquiring the Dr. Ph. Martin's Set #2, & it occurred to me that painting a color chart is a great introduction to your materials, while simultaneously removing the pressure to produce "art." The first block I painted was the sepia, as a lefty I work from the upper right across the page. It was so granular that I am emailing the company today to find out if this is usual. Rest assured I had thoroughly shaken the bottles before testing, as who knows how long they were on the shelf. The burnt umber & sap green also had some granulation, but nothing compared to the sepia. If I had not done the color chart I would not have known this paints attributes & might have mistakenly placed a dropper of them on a painting expecting them to morph in the manner of the others. I would have wrecked a painting. So what am I saying with all of this? Check your materials whatever they may be, know their properties & attributes & learn how to best work with them. I am sure there is a life lesson in there. Happy Tuesday Y'all!
P.S. Contacted Dr. Ph. Martin regarding the sepia. Response within 5 minutes, new bottle on the way. Customer Service for the Win!
