I picked up an Imperial Knight awhile ago, and decided to go with the Hawkshroud house. Mostly because I wanted to try my hand at airbrushing yellow again. It was also my first project since receiving the Angel Giraldez book.
I primed all of the secondary areas with black and grey, while I primed all of the future yellow areas with white.
You have to paint yellow negatively, (meaning light to dark). 4 coats of Moon Yellow.
You have to look closely to see the next layer, but I began shading with Sun Yellow.
I added the deepest shades with Orange Rust, and added highlights with 50/50 White, Sun Yellow.
More to come.
