I have finished my base colors for the Sonic Dreadnought and it is coming along well. The pink has dried p but I remember the formula. It was 1 part Mechrite Red to 2 parts Bleached Bone. That gets painted over a Mechrite base then washed Carroburg Crimson then touched up with the pink mix.
The goal was to make the Dreadnought match my Noise Marines and the Daemonettes. I am sad that there are so few armor plates to paint. The plan was to alternate plates pink and black with gold trim to match the Champions but with so few plates, I had to alternate more than I wanted. I needed more black on the model.
I am liking how it is turning out so far.
