A flag is one of the most recognizable symbols that a country can have. Flags come in different color combinations. Some have only two color combinations while others may have up to six colors (such as the flag of South Africa or the flag of South Sudan). Blue and yellow are some of the common colors on flags. Several national and regional flags are only made up of the two colors. However, the color shade may vary from dark to light yellow/blue. Here are some well-known flags that feature blue and yellow:
