Virginia law states (my highlighting added):
“Equipment
Every bicycle ridden between sunset and sunrise must have at least one white headlamp with the light being visible at least 500 feet to the front. The bicycle must have a red reflector on the rear visible at least 600 feet to the rear. On roads posted with speed limit of 35 mph or greater, the bicyclist must additionally be equipped with at least one red taillight visible from 500 feet to the rear. Taillights may be steady or blinking, are allowed under all conditions, and may be attached to the cycle or rider.
Bicycles ridden on highways must have brakes which will skid the wheels on dry, level, clean pavement.

I’ve seen cyclists with red lights on the front of their bikes and find that confusing. I recommend against red in the front or white in the rear.
Because seat tube space is often at a premium, I have two tail lights on my left seat stay. My spokelights are non-red/white and I’d hope that motorists would see the movement of the spokelights well before they get close.
