Why do aircraft default to white?

IIRC, white was used on the British V-bomber force to help protect against the flash of a nuclear device going off below.

A real laugh flying for the V-bomber force, to compensate for blinding nuclear flashes, the RAF came up with the following scheme. The pilot would fly with one eyepatch and the co-pilot behind a blind over the canopy. When blinded the pilot would remove the eyepatch and fly until completely blind, then the co-pilot would remove the blind and wear an eyepatch, flying until blind himself :dubious: and :eek:
