Each spring, the Gamblin Company cleans its particle filtration system of all the pigment dust collected over the year, and tubes it as "Torrit Grey", a complementary grey. The color and value of Torrit Grey is different each year - often, according to the Gamblin folks, because of the proportion of Pthalo dust in the mix.
Each year, Gamblin holds an
online competetion for artists, who are allowed to use black, white, and Torrit Grey only.
This June, I conducted a 3-day Torrit Grey workshop for the Scottsdale Artits' School; the Gamblin marketing people supplied the tubes of paint for the students. I opened one of the tubes and tried out the grey beforehand (and am SO glad I did !) The color has a VERY srong staining violet cast. Only in class, when we opened up the other tubes, did we find that there were actually 2 different colors tubed this year - the second is a much warmer, non-staining color. As I experiment more with the second color, I'll add to this demo.
I began by creating a color chart. The top row is comprised of 5 values, using black and white. The middle row has 4 values (Torrit Grey out of the tube is at the second darkest value level) and uses only Torrit Grey and white (Titanium). The third row uses all three colors. It may be difficult to see on the your screen, but the TG +TW has distinctly violet cast. I gave students canvas scraps so they could practice mixing before beginning their paintings.
