Blue layer.

These are with the blue layer on top – prolly another two to three layers to go on the tiki, dunno about the other one, but I’m warming to it 😀

The tiki image is a shade more blue than that over all, and the Yellow is stronger too, but I can’t get it any closer without major photoshopping, the other one is fairly close to life;

Gum bichromate has really interesting optical qualities, it changes in light, which is fun, but also as you move past the image – the reason for this is that there’s reasonably thick (microscopically thin, but optically thick) layers of gum arabic that build up, each with pigments in them – so the colours spectrum shift, filter, and do all sorts of interesting stuff when light hits them.
