…asked Time Magazine in its “Answers Issue”, Sept. 8–15, 2014.
After downloading images of 196 national flag from Flagpedia.net, Time added up the number of pixels of each color, simplified them, and grouped them into categories of white, black, red, blue, green, and yellow using a simple algorithm.
Time thus determined the frequency of colors by area in national flags. Although perhaps flawed in detail, overall it is a sound analysis.
