Most Visible Color for Aircraft

Howdy,

I've been looking all over, and I can't seem to find any discussions on the
relative visibility of various colors for aircraft. I would guess that the
best color might be different when viewed against the sky or the ground.

Any pointers will be welcome,

The Coast Guard probably did some study before it painted its
helicopters.

Which is why they have the same color scheme as their boats? Uh, sure.

I think the original poster's guess is correct, that it depends on whether
you're looking at the airport against the ground or sky. I would expect
dark colors to stand out better against the sky, and light colors to stand
out better against the ground.

That said, for overall visibility, the fluorescent yellow/green used on many
traffic signs and emergency vehicles is probably the most visible color.
Also, keep in mind that the color is probably only going to make the most
difference when close to the aircraft. At a distance, contrast will still
be an issue, but against the sky, pretty much any airplane will just look
like a shadow, regardless of color.

Of course, up close is when you care most about seeing the other aircraft,
so it's not as if the question is simply academic.

Light on top, dark on bottom?

If you have ever been in the pattern with a Piper J-3, you must know
that the best color is Cub Yellow.

I live in New Hampshire, where most of the ground is covered by white
pine. For several years there was an L-4 wannabe (a J-3 painted up as
a Grasshopper) used for training at the local airport. It was a bear
to spot in the pattern, especially if you were higher. Name of Nine
Seven Mike.

Happily someone banged up a wing, so while it was in the shop, it was
painted with invasion stripes on that wing only. You cannot believe
the difference those two? three? stripes made!

Later, someone else banged up a wing the second time, but alas it was
the same wing, so I never got a chance to see if a second set of
stripes would have improved things even more.

Nine Seven Mike has since been sold down the river, so you may see it
at your airport.

Article in Passagemaker boating magazine cited the coast guard who rescued
some sailers in the water who were wearing flotation suits of safety
yellow.. The chopper crew agreed that if the suits had been orange or red,
they would have missed them... They could not see the international orange
raft that was drifting nearby, but the yellow suits showed against the haze
like beacons..

Probably not true. When I started flight training in Pensacola in
1958, all of the Navy's trainers (T-34, T-28, and SNJ) were painted
"Cub Yellow". By the time that I graduated 18 months later, after
extensive research, the Navy had repainted their training fleet to
the current color scheme, white and red. This is of course the same
as that used by the Coast Guard and has lasted for 45 years.

The Coast Guard choppers that I see around Puget Sound are red with a white
stripe.

Right, and fire engines used to be red but now are yellow.

Perhaps because the navy and the Coasties can ensure that their
population doesn't include color-blind, while the population at large
cannot?

All the fire engines in our town went back to Red after a decade of
yellow/green.

It was found that Lighting is much more important than the color for
visibility.

And when our fire trucks were yellow/green the public thought they were
highway/garbage trucks. We went back to Red because that's the color
the public most associates with fire trucks.
