BruceZed,

Although these colors work great in most situations there are areas, particularly in the American Southwest where red, yellow and orange disappear into the background. White is often the best there, except in winter. I have had trouble finding someone from the air several times for this reason.

Respectfully,

Jerry

AKSAR,

I had the same problem near Point Lay, but this was before GPS and the individual had done a transect but missed the pickup point. Had to fly slowly down the river at about 50 feet to see him in his navy coat.
