The Texas flag is known as the "Lone Star Flag". This flag was introduced to the Congress of the Republic of Texas on December 28, 1838, by Senator William H. Wharton. It was adopted on January 25, 1839 as the final national flag of the Republic of Texas.
When Texas became the 28th state of the Union on December 29, 1845, its national flag became the state flag. While the Lone Star remained the de facto state flag, from 1879 until 1933 there was no official state flag. All statutes not explicitly renewed were repealed under the Revised Civil Statutes of 1879, and since the statutes pertaining to the flag were not among those renewed, Texas was formally flagless until the passage of the 1933 Texas Flag Code. The code assigns the following symbolism to the colors of the Texas flag: blue stands for loyalty, white for purity, and red for bravery. The official Pantone shades for the Texas flag are 193 (red) and 281 (dark blue).
