Around sunset, a white and light blue light flashes at my airport. What do these colors signify, and do other airports have different colors for particular reasons?

White and Blue don't ring a bell.

Are you sure it's not green and white - means civil airport...

What you see is the rotating becon. It is white and green. At a civilian airfield, it flashes white, green, white, green... At a military airfield, it has the same colors, but flashes, white, white, green, white, white, green... This is just to highlight military fields from civilian fields. The becon, itself identifies the airfield at night. It is also turned on in the day if it is only IRF conditions. If you are seeing any other color that Green and white, you are most likelyu looking at a heliport.

I thought blue lights indicated a K-Mart special.

PureMuscle is probably right. Trust me, I've seen a few airport beacons (in Virginia) that really are BLUE instead of green. Not light green, not bluish green, not greenish blue, but blue.

What else did you see? Gremlins? Knomes? Rainbow colored dancing bears?

Just kidding with you! ;)

My guess is the lights are just super old and the color tinting is too faded. Or someone is playing a dangerous joke.

I don't think that's the case. I think somebody figured it was close enough. Not a joke because I've seen them at more than one airport, but primarily the one a few miles away, which I drive past all the time.

I believe that it was and is indeed "blue" light... Have you ever taken a good look at the so called "aviation green" position lights on our aircraft? They are also quite blue!

Why is this? It is so that our rods, the light sensors in our eyes that we use for night vision, also participate in the seeing of the "green" light of the beacon. It makes it more visible at night out of the corner of your eyes since the rods are most sensitive to blue green wavelength.
