The flag of the state of Nevada consists of a cobalt blue field with a silver star in the upper left hand corner, surrounded by the state name "Nevada." Above this is a golden-yellow scroll with the words "Battle Born," indicating that Nevada became a state during the American Civil War. Below the star are two sprays of green sagebrush (the state flower) with yellow flowers.
The current flag had its origin in a design contest announced in 1926. The winning design, by Louis Shellback III, was subjected to some revision in the state legislature, where there was disagreement between the two houses over the placement of the word "Nevada" on the flag. A compromise was reached, and in 1929 Governor Fred B. Balzar signed into law a bill adopting the new flag. In 1989, however, a legislative researcher discovered that the bill as sent to and signed by the Governor did not accurately reflect the 1929 legislative agreement. A law enacted in 1991 directed that the word "Nevada" appear below the star and above the sagebrush sprays, thus producing the current design.
The first flag of Nevada was created by Governor John Sparks and Col. Harry Day in 1905. It was based strongly on Nevada's natural resources of gold and silver. The blue of the flag was based directly on the color of the flag of the United States.

Nevada State Flag Symplistic Proposal. The blue stripes represent cooler climates that surround the state and the red bar in the middle represents the desert. The bar also represents a bar of silver, taken from the state’s nickname, “the silver state.” By Ed Mitchell. 2013.

My version of a design by Hans. Blue and silver are the official colors of the “Silver State.” The state’s territory was originally named Sierra Nevada or “Snow Capped Mountains” by the Spanish, hence the white-capped mountain. The star represents the state itself and is positioned in the canton similar to the current flag. Posted by Preston Knapp
