More specifically, the left ear. The 501 CRL states that it is olive green, as opposed to the minty sort of green used on the rest of the helmet. However, it looks like a lot of people are keeping the ear either really close to or the same green used on the dome and cheeks. I used the same green on the dome, cheeks, and left ear as a result of this. Should it be a more yellow or olive tone?

yes it is. Mods, you can delete this thread.
