What are "invasion stripes"?

Sets of alternating black and white bands on the wings and fuselage. With the
exception of some of the high-level bombers, all Allied aircraft that were
expected to fly over Europe in support of the invasion of Normandy were painted
with these. The idea was to keep our troops from shooting at our own aircraft.

They don't necessarily make an aircraft more visible, but they allowed troops
to figure out at a glance whose side the plane was on if they saw it.
