What color coding system is used to identify the age of queens in beekeeping?

The color coding system used to identify the age of queens in beekeeping corresponds to the year in which the queen was born. Each year is assigned a specific color, and this system allows beekeepers to easily determine the age of a queen when inspecting a hive. The correct sequence starts from white for queens born in years ending in 1 or 6, yellow for those born in years ending in 2 or 7, red for years ending in 3 or 8, blue for years ending in 4 or 9, and green for years ending in 5 or 0.

This system enhances beekeeping practices by allowing the quick assessment of queen age, which directly influences the hive's reproductive capabilities and overall health. If a queen is older, she may need to be replaced; thus, knowing her age at a glance aids in maintaining an optimal bee colony. The answer provided reflects the correct color coding used in this context.
