Which two natural elements are a prominent part of Rossi's livery and helmet designs?

The Sun and Moon are indeed the two most prominent natural elements in Valentino Rossi's helmet and livery designs. His iconic helmet features a bright sun on top and a crescent moon, often depicted as smiling or winking. This celestial theme has become Rossi's trademark visual identity throughout his career across different manufacturers (Honda, Yamaha, Ducati). The sun and moon represent the duality of day and night, and Rossi has said they represent the contrasting sides of his personality.
