The previous ink layers were still a little tackier than I wanted, but I decided to dive in anyway.
As a reminder, the linocut was at this stage:
The diffuse band of darker pigment was working nicely, but I still wanted a bit more.
I (almost) always save the remains of the inks I mix at each stage of a print. Very often those scraps become the basis of subsequent color passes, and that was the case here. Monday's transparent gray went back on the inking table today, with a little more black and blue pigment added for this final pass.
Unfortunately this isn't a great shot– there's glare across the right-hand image– but you can see the blue-black in the lower right corner defining a few more twigs and adding more depth.
I thought that would be it, but I wasn't quite satisfied with the shape of that dark.
