Which airspeed limitation is not color coded on airspeed indicators?

Explanation:
Airtpeed indicators use colored arcs to show the airplane’s safe operating envelope: the white arc marks the flap operating range from Vs0 up to Vfe, the green arc covers normal operations from Vs1 to Vno, the yellow arc indicates the caution range from Vno up to Vne, and a red line shows the never-exceed speed, Vne. Maneuvering speed (Va) isn’t fixed like these limits; it changes with weight and configuration and is not represented by a fixed color mark on the scale. Since Va varies, it isn’t color-coded on the ASI, whereas Vs0, Vs1, and Vne are fixed limits that do appear as the endpoints of the colored ranges or as the red line.
