On March 15, 1925, this flag was adopted by the U.S. state of New Mexico. It’s a widely liked flag for (imo) good reason. The design is simple and striking, the colors go very well together and fit a relatively arid state, and the Zia sun symbol does a great job distinguishing this flag from others.

My favorites are probably the flags of and They have really appealing colors imo, and the symbols are great as well (especially Niiagata’s).

It represents the blood that will be spilled in Utah’s conquest for world domination.

In all seriousness, it’s meant to evoke a rocky canyon. Additionally, the white is meant to be mountains (hence the shape), and the blue is sky.
