Geographic Flag of Diego Garcia

The Geographic Diego Garcia flag is a tribar of white, purple, and orange- which indicates a Longitude of 72 Degrees East.  The central stars of white and purple indicate a Latitude of 7 Degrees South. 

Diego Garcia is the Midway of the Indian Ocean, or rather, Midway is the Diego Garcia of the Pacific Ocean?

The colours are coded to numbers.  And the code is based upon the order of a rainbow.  Orange is 2, since it is the second colour.  Yellow is three, since it is the third colour and so on.
