How Colorado Made Blue and White Official

Colorado's General Assembly designated blue and white as official state colors in 1911, the same session that adopted the state flag. The flag was designed by Andrew Carlisle Johnson of Denver, who built the design around the two colors. Blue runs across the top and bottom stripes, white fills the center.

The 1911 act left one thing unresolved: the exact proportions of the letter C on the flag were never specified. In 1929, the legislature returned to the flag and standardized the dimensions. The colors themselves have remained unchanged since the original act.

What Colorado Colors Mean

When Colorado adopted blue and white in 1911, the blue columbine had already been the official state flower for twelve years. The colors formalized a connection the landscape already made obvious. No official Pantone or HEX was specified in the original act.

What Colorado Blue Means

Blue fills the two horizontal stripes of the Colorado state flag and the distinctive letter C. When the legislature chose it in 1911, they linked it to the Colorado sky and the blue columbine, the state flower since 1899.

Meaning of Colorado White

Snowpack on Colorado's peaks stays year-round above 11,000 feet. That enduring presence is what the 1911 act captured in the center stripe: a band of white between two blue bars.
