Here are the next couple of stages of the paintings. Above you can see that the cows are still in their metallic blue phase but some modifications have been made to the background hills. The right and left hand thirds of the hill-scape have been coated in a thin layer of interference blue while the middle section is now coated in interference yellow (the latter being created by mixing some cadmium yellow with some
pearlescent tinting medium).
Once dry the trees and hedgerows were added in a loose style.
In the second pic (below) I've started to "knock back" the shimmer from the interference blue on the cows by over-painting the cows with
interactive acrylic.
When applying the paint at this stage I'm just painting as I would normally, regardless of the fact there is interference acrylic beneath. When the painting is finished I want any interference blue that shows through to be serendipitous in nature and not look "planned".
