Persian blue (not to be confused with Prussian blue) comes in three major tones: Persian blue proper—a bright medium blue; medium Persian blue (a medium slightly grayish blue that is slightly indigoish); and a kind of dark blue that is much closer to the web color indigo; this darker shade of Persian blue is referred to as Persian indigo, dark Persian blue, or regimental.

Other colors associated with Persia include Persian pink, Persian rose, Persian red and Persian green.

The color Persian blue is named from the blue color of some Persian pottery and the color of tiles used in and on mosques and palaces in Iran and in other places in the Middle East. Persian blue is a representation of the color of the mineral lapis lazuli which comes from Persia (i.e. modern Iran) and Afghanistan. (The color azure is also named after the mineral lapis lazuli.)

The first recorded use of Persian blue as a color name in English was in 1669.

The medium tone of Persian blue shown at right is the color called Persian blue in color sample #178 of the ISCC-NBS color list.

The source of this color is the ISCC-NBS Dictionary of Color Names (1955), a color dictionary used by stamp collectors to identify the colors of stamps, now on the Internet—see sample of the color Persian blue (color sample #178) displayed on indicated web page: [2].

The color Persian indigo is displayed at right. Another name for this color (seldom used nowadays) is regimental. The color was called regimental because in the 19th century it was commonly used by many nations for navy uniforms.
