Is there a medium available that can thicken paints but not necessarily 'thin' the pigment too much?
Lifecolor makes a thickener which I picked up a while ago. I've only used it a couple of times but seems to work. If the paint is really low pigment though you can get that effect where you're just pushing the paint around the surface.https://www.snmstuff.co.uk/product/lifecolor-thickener-22ml/
Put a good amount in your palette well,wait till it forms a skin on the surface,break skin before it dries out (haha,obviously).I use this system for dry brushing trees, buildings et cetera, before oil washes...
