Northern gannets have a beautiful yellow/pale ochre tint to their head feathers, so I tackled that next. The two small areas of the block were inked with a 1-inch-wide brayer and an acetate mask.
A wee bit more carving and a second, slightly darker ochre was applied using the same mask and 1-inch brayer.
Okay, good. And now... the gannets' bills needed to be a wee bit more blue than the color that went down on the first pass. I cut a second mask and employed the 1-inch brayer one more time.
