Zapper, I know that the lime yellow instruments are unique to the JPE edition and that you were trying to recreate it in Stunts as accurately as possible. I don't mind the original colour scheme, but I admit that the needles are a little difficult to see. My suggestion was based on the idea that if you're going to change the colour scheme to improve visibility, then simply use the most contrasting colours that also look appealing. Otherwise, leave it as is in the name of accuracy.
In saying that, in the attached photo, the instruments look quite close to lime green anyway.
