Orchestras are tuned to A = 440 hrz
Visible Light wavelengths from 380-750 nm
Stars get their color from the elements they burn.
E5 is 659.25 hrz
Red is 625-750 nm
Therefore, by the power of arbitrary correlation, E5 is red.
But wait, there’s more!
Invoking the power of arbitrary correlation, we can associate the color to atomic matter.
Hydrogen stars burn red.
