Finding images of wolves comprised of either intense shadow, ash or light was pretty difficult – not due to the lack of content, but the wading through excessive amounts of poor renderings and depictions in the form of DeviantArt ‘OCs’. Fortunately, the excess of those meant that the good references were indeed very good.
I assembled the images into a spread of varying colours, and then created my colourboard from that, trying to create a fragmented set of tones that would reflect the fragmentation of the antagonist.
We ended up with a nice range of colours, mostly deep greys and reds, with some blue and green tints to act as highlights against the skyline. Hopefully, this palette works well for us. Time will tell.
