The flag was later adopted as the state flag when Texas became the 28th state in 1845. As with the flag of the United States, the blue stands for loyalty, the white represents purity, and the red is for bravery.

The official description of the Texas flag, which specifies the exact proportions of each of its elements, was only recently adopted by the state legislature. Accordingly,

"The state flag consists of a rectangle with a width to length ratio of two to three containing: (1) a blue vertical stripe one-third the entire length of the flag wide, and two equal horizontal stripes, the upper stripe white, the lower red, each two-thirds the entire length of the flag long; and (2) a white, regular five-pointed star in the center of the blue stripe, oriented so that one point faces upward, and of such a size that the diameter of a circle passing through the five points of the star is equal to three-fourths the width of the blue stripe."
