Red Baron Color?

I'm looking for the color of the famous Red Baron air plane, would someone have any clues of where I could find a code or a receipe?

I'm planning to use Sherwin Williams paint because that's what I sell at work, but I could always convert a PPG or Dupont receipe if someone have it..

I saw that they did a flying car on Monster Garage that used the same color, but it was made by House of Kolors, but it's not available around here..
