Whic countries flag has the most colors?

My completely unscientific review of the flags on the CIA web site suggests that the Cayman Islands wins that distinction:

(And here's the list: https://www.cia.gov/library/publications/the-world-factbook/docs/flagsoftheworld.html)

South Africa's

1) It depends if we just count the main colors on the flags or also the colors on a coat of arms which is eventually included in the flag.


2) I think this applies only to the main colors:
- "The national flag with the most colors is South Africa’s, with 6."
http://en.wikipedia.org/wiki/User:Reywas92/Trivia

" Table 3 shows where the numbers of colours on flags are located in the world in 1999. It is interesting to note that the only countries using a single-coloured flag (Libya) - the least number of colours currently used on a national flag - and a six-coloured flag (South Africa) - the most colours on a national flag - are both located in Africa."

However, the table indicates *two* countries in Africa with a six color flag.


3) Those statements probably consider also the coat of arms on the flag.

"Pictured here are the flags of the Netherlands, the USA, and the flag with the most colors, Saint Pierre and Miquelon."

Note, however, that Saint Pierre and Miquelon is not a sovereign state.

Some interesting flags are also those of Paraguay, Moldova and (in a less extent - bicolor) Saudi Arabia, because obverse and reverse differ.

"The flag of Turkmenistan (Turkmen: Türkmenistanyň baýdagy) was adopted on January 24, 2001. It is often described as the most detailed national flag in the world."

I would say Comoros in Africa which has 6.

South Africa has quite many.
