The Transgender Pride flag was designed by Monica Helms, and was first shown at a pride parade in Phoenix, Arizona, USA in 2000.
The flag represents the transgender community and consists of five horizontal stripes, two light blue, two pink, with a white stripe in the center.
Monica describes the meaning of the flag as follows:

"The light blue is the traditional color for baby boys, pink is for girls, and the white in the middle is for those who are transitioning, those who feel they have a neutral gender or no gender, and those who are intersexed. The pattern is such that no matter which way you fly it, it will always be correct. This symbolizes us trying to find correctness in our own lives".

The flag was flown from a large public flagpole in San Francisco's Castro District beginning November 19, 2012 in commemoration of the Transgender Day of Remembrance ("Transgender Flag Flies In San Francisco's Castro District After Outrage From Activists" by Aaron Sankin, HuffingtonPost, November 20, 2012).

On 19 August 2014, Monica Helms donated the original Transgender Pride Flag to the Smithsonian National Museum of American History.
