Two things.
1.most important, its the actual numbers that are important, not the colors. The colors serve as a general guide line, but its the actual numbers that matter. Example is Shwarzkopfs are known to reach up to 6Gs, but by defult that would be red in NL2. (You can also change what the numerical value in which the colors change)
2.Keep in mind for flyers Acceleration Gforce, and Vertical Gforce are switched around as you're oriented differently.
Agreed for #1. The reason why I stick to the default range given to the colors though is that it is the range generally considered to be comfortable. But it can be safe (if barely) - Tower of Terror at Gold Reef City in South Africa pulls 6.3 Gs and is basically a rollercoaster that drops from the top to the bottom of an oil tower. NoLimits says 5.5 is the red limit for vertical G forces, but Schwarzkopf disagrees, (almost) every time.
I think the important thing though is not just the magnitude of the force, but how long it has been applied. There's a reason why a 4G drop with 4G only being applied for a second is considered not so bad while Goliath's 4G helix can make riders black out - the former has the riders experience 4G for a moment, while a highly banked helix, which goes around and around, applies that 4G to riders for seconds on end. Even 3G for too long may not be good. So I dismiss a little, momentary "red alert" before a near-circular loop for a Schwarzkopf coaster remake, but when seeing a B&M recreation with a 6G helix that lasts for 10 seconds you know there is a problem.
Didn't know about #2 though.
