The yellow field and red symbol colors are the colors of Spain. On New Mexico's flag we see a red sun with rays streching out from it. There are four groups of rays with four rays in each group. This is an ancient sun symbol of a Native American people called the Zia. The Zia believed that the giver of all good gave them gifts in groups of four. These gifts are: The four directions,The four seasons, the four times of day and stages of life.
