I recall during WWII, maritime patrol bombers used bright white lights on

their leading edges as camoflage so they could sneak up on U-boats without

After a comprehensive study by the RAF it was found that the colour which
was most conspicuous in a wide variety of daylight conditions was black.
The colour which was least conspicuous was, you guessed it, white or light
grey. Strobe lights are not very effective in bright daylight conditions
and when do we do most of our flying? When the sun shines.
There are very good technical reasons why the top surface of a glider must
be white but does the underside have to be?
