Gamblin makes Portland Greys, literally inspired by the Portland skies when not ablaze.
The concept is that in making one's own greys the more white one ads, the more blue the greys get, or at least cool. So when working with values one tends to have temperature intrude.
I can't avail myself of the Gamblin at the moment, but was wondering what one could use to mix. Gamblin gives one all the component colours. Was wondering about some burnt sienna added.
If one is a Zorn user, then one knows that both the black and the white, are the blues.
Has anyone owned this problem yet?
