The first, albeit short lived, pride flag was similar to the colours as above, though reversed with pink at the top (Pink, Red, Orange, Yellow, Green, Turquoise, Indigo, Violet). It was soon after that the pink was removed due to cost/availability (can’t remember exactly off the top of my head).




It seems that the turquoise stripe was dropped, …“to create an even number of stripes for display on each side of the streetlamps on Market Street for the 1979 Gay Freedom Day parade.”

The pink was due to availability by the Paramount Flag Company when they started being made beyond what could be handmade.
