So, I don’t have any experience w airbrushing or makeup, but I know a couple things about skintones. Here’s what I would do, in theory; in practice, I have no idea if this would work.

1.) cover the whole thing in matte white primer
2.) cover the whole thing again in a very pale slightly yellow-ish peach; this should be as close as possible to your base undertone, the parts that aren’t rosy. For me, my thighs are the best option for finding a relatively large swath of undertone.
3.) airbrush patchy light pinks in multiple layers to mimic skin texture; use your own skin, esp your ears, as a guideline.
4.) add a tiny bit of lavender, also in layers, to parts that are more shadowed.
