Anyhow, the color is not a fixed value that is a must to reach. If you get blue you have something similar to 80% usable servo throw. The further you can go the higher the value will be. So everything from blue upwards will give a good resolution and you won't feel any disadvantages. If using good, precise high class servos, strong and with fast speed you even can fly with only red LED without any noticeable difference. Also rotorblades (flybarless blades or not) can make a difference. On a 250 or 450 size heli you should try to get "dark blue" at exactly 6.0° as here servos normally are not so precise.
