What color codes are used for prop-rotor blades?

Explanation:
Color markings on prop-rotor blades are there as a quick visual reference to aid safety, inspection, and maintenance. Painting distinct bands at fixed locations along the blade lets you rapidly assess blade condition and alignment as it moves or during ground checks. The red, green, and white combination provides high contrast and a familiar progression from the hub toward the tip, making any bending, cracks, or paint wear easier to spot. That standard three-color scheme is why red, green, and white is the correct choice.
