Navassa Island Geographic Flag

The Navassa Island Geographic Flag is a tribar of white, purple, and blue.  The colors are coded to numbers based upon the rainbow.  The central star represents the Latitude of 18 Degrees North.  See the Flag Key below to make sense of the number to color symbolism.

Note this is an apolitical, scientific, objective flag that any nation can fly.  This makes these flags useful in disputed areas.
