When painting the Marines Malevolent, I encountered a small problem: the way I paint usually was not suitable for painting yellow armor. Usually I go from dark to light through a lot of layers, but in this case it gave a sad result, since yellow is very difficult to work with. I tried to go from light to dark, but it gave too little depth and color saturation.
In the end, I decided on the method used by a fairly large number of painters: I did a contrasting underpainting and then painted on it.
So, at first, I covered the black undercoat with a layer of Khaki (Vallejo Game Color) [Fig. 1] and then made base mixes for underpainting. For this purpose I used Brown, Dark Tangerine and Yellow from Pacific88 Art-Color.
Then I started to use shadows in a similar manner, only using brown and dark tangerine with different proportions for glazing. [Fig. 4]
And, finally, I drew additional details of black and battle damage by the brown and a mixture of yellow and pearly white [Fig. 6]
