A website that统计s the color distribution of national flags allows users to guess the flag through a pie chart showing the proportion of colors in the flag. Upon opening the website, you can click on the color ratio chart to see the corresponding national flag, and by clicking on the flag again, you can view its color ratio chart. At the bottom of the website, there is an overall statistical ratio chart, where white is the most common, and the three primary colors—red, green, and blue—are relatively concentrated.
