Problem with the HUD

I know that I am partially color deficient, I cannot see when or how far the tach goes into the redline on the HUD. I cannot stand the digital tach and have always been able to see the analog tach in the other Forza games. It just seems like the needle (not really a needle but a faint change in tach outline color) is too faint and the red part of the tach doesn’t change enough color to see it, at least for me. I just wish the needle on the tach had more contrast.

I am sorry if it seems petty but it really is hard for me to see.
