Is it just me or does anyone else notice that at night, the white beacon flash can actually look a little green. Is this just because the light may be reflecting off the green lens on the other side? I'm guessing this is the reason because I can always clearly make out the lights for heliports (three light beacon). The only reason I ask this is because I just want to know if I should pay a visit to my AME.

I've never noticed any other color but white. I think the green looks blue, but it actually is a more teal color than green.

7574EVER,

Next time you do a night flight, have your friendly local control tower flash you some light gun signals before you go to the AME. If you can't distinguish the colors then you may have an issue. I have a friend who had an issue with red/green color blindness and he had to go through quite an ordeal to get his medical back. I would agree that 'green' isn't the best way to describe the color of the beacon. Unless the field is out in the middle of nowhere it does look teal. When there is a dark contrast around it in a rural area it looks like a darker shade of green in my mind.

You should be given a red/green colorblind test during your FAA physical...

Anyway, one side is white, the other is supposed to be green, but I've seen em from blue to a green so faint it looked white.

Could it also be possible that he is seeing some green due to light refraction? I'm not sure where he is in relation to the beacon, but it could be a possibility  Smile.

Goldenshield,
I think that's most likely the case. Like I said, the colors on heliport beacons are as clear as can be.

It could also be the type of bulb used. I believe that the one at my old airpor was a mercury bulb, and it burned blue-ish. You could definately distinguish from the white and green though.

At my home airport, the green lens fell off, so for the past week or two we've had two white!

Not really pertinent, but interesting.
