The use of flags goes back 3,000 years. People have raised flags on Mount Everest and the Moon. Red is the most popular color used on a flag, with about 75 percent of all national flags using that color. White is a close second, used on about 70 percent of the national flags, and blue is on 50 percent of the flags. Green, black, orange and yellow are some of the other colors used.  Only one national flag uses purple – do you know which one? What would your personal flag look like?   Purrs, Gulliver
