Hi Zac,
I'm an enamels guy myself, but acrylics work the same, use basic colors you have, yellow and red, then mix them together until you get a light orange color that matches the chrome yellow color chip. And don't forget, the Jasta 10 chrome yellow was not a color supplied by the German army, it was by no means a standard color so it was probably mixed in the field, so much red added to that can of yellow until it looked like Herr Voss's cowl... you get the picture!
