Here are some (heavily compressed) pics of these cavern pieces, step 1 and 2. I’ll blog painting this, and I don’t know how they’ll turn out, so before following what I do check the end pics and decide if you like the result or not 🙂 .
Step 1. Background wall.
Blob of white, about half that of yellow oxide, a drop of raw umber to darken it.
I think of cave formations as being yellow, because they are usually lit with tungsten lights. Calcite is actually white. But meh – it will get sorted out. The yellow oxide gomes out a little greenish, but that might be the light I am using.
I do the walls first because the are heavily textured, and you get paint all over your hands doing them. Stiff cut-down brush, plenty of paint on it, get rough with it. 95% coverage is good enough, because the deeper cracks will get darkened anyway, and the dwarvenite is a dark gray.
Main thing is not to go to heavy and clag up the detail. Oh – on the standard wall pieces, paint tends to collect under that top scalloped bit of flowstone in the middle. Give it an extra stroke with the brush to clean it out.
Step 2. Floors.
This took me a lot of faffing around with to get a mud brown. The main thing is burnt sienna. I would have liked a burnt umber to keep the palate simple, but meh. Reddish brown, a little yellow makes it a rich chocolate, Atelier ‘brown black’ to darken it, white to lighten it and reduce the saturation. Eventually I got a colour I liked – kinda.
Broad cut-down brush to do most of the floor, then a finer brush to get to the edge between the floor and the wall. Main thing to watch for is paint on the fingers, so after that first step of painting most of the base wash hands and take a little more care. You’ll note that a lot of the dwarvenite colour shows though, and the lighter mud shade has collected in the cracks, which is not the effect I want. Hopefully, the dark wash will fix it.
I don’t know if darkening the sides of the pieces (where they touch one another when assembled) was a good idea or not. The problem is that the edge around the base definitely needs to be dark, but there’s no logical place to stop when doing those side edges. So meh. When painting those edges, you get a little slop onto the wall surface – which you don’t want. Wipe it away.
After this gets tacky dry, some spot clean-ups with the wall colour and a fine brush. At the very least, clean up the worst of the finger marks.
