Topic: Different Colors for HUD of F16

I have been away from flight simulation for some time. Having returned to flying the F-16 I find that the light green color on the HUD very difficult to see especially when banking the plane. Has there been any updates which have added darker colors to the HUD. I am 80 now and my eyes are not what they used to be. I would appreciate some information on this subject.
Thank you
