The ring's color changes depending on the attenuation model chosen,
and whether Max Distance is capping the distance the sound can be
heard at.

Cold colors are used when the volume cap is a "soft" cap (the sound
can still be heard past the distance, but only faintly).

Warm colors are used when the volume cap is a "hard" cap (the sound
can't be heard past the distance at all).

White is used for linear fade performed when the attenuation model
is Disabled and Max Distance is greater than 0.

No ring is drawn when the attenuation model is Disabled and Max Distance
is equal to 0 (since the sound can be heard from anywhere).
