In the mail today I received two tubes of Gamblin Torrit Grey, their special (and free!) grey. Not an ordinary color, once a year Gamblin scrapes their Torrit brand air filters of stray pigments and mix up a batch of unique paint. Each year the combination is slightly different, making me think of starting a very careful and extensive collection of all vintages of Torrit Grey.
I ordered the tubes because, besides being just a cool idea, this is kind of an amazing conceptual artwork.
