Language indicator flags are based upon modified national flags on a field of navy blue or sea green. Here is the language flag for English. Subsequently it has the flag of England in the canton and the field is navy blue. Finally it has a sea green stripe upon the end divided by a white vertical stripe.
As opposed to the English flag which could indicate England or some kind of political stance, the distinct sea green and blue field symbolize that English is spoken. The colours of navy blue and sea green reflect that language is the water element of a persons identity. Like the water that fills a glass, whatever environment your early mind is shaped in, you will take on that identity-accent. Learning a language is like learning to swim, it takes time, practice, and eventually an ocean of information overtakes the mind. Many people can only swim or sail in one type of ocean. Most persons who are native to the English Ocean in the United States can paddle a little bit in the Spanish Ocean. But nearly everyone in the United States can splash around in the kiddie pools of France, Japan, or China since they may know a few words: like Bonjour! Shay Shay? Oui! Domoarigato! It takes time and a lot of practice to sail in difference Linguistic Oceans, especially if you are a native to the English Ocean of Speech.
Remember that most people in Canada and the United States may speak English, yet are not English. Thus one should not confuse language with ethnicity as often is the case with Spanish speakers, since there are many people who sail the Spanish Ocean their entire lives, yet have do not one drop of Spanish blood in the heart. Once again, there are many people with English names in the USA who live their entire life in the English Ocean and have absolutely no English blood flowing in their veins.
Thus this flag is the primary language flag of: Scotland, Ireland, Canada, South Africa, New Zealand, Jamaica, the United States, Australia, Wales, and of course England. This is also the dominant language of the world in terms of commercial and international communication.
