The Philadelphia Flag is possibly one of the most used variations of the rainbow flag, aside from the Progress Flag, which it probably partially inspired.

It added black and brown stripes to highlight racism within the LGBTQ+ community and was designed as part of a collaboration between Philadelphia's Office of LGBT Affairs and the company Tierney. It was the first change to the rainbow flag to be "officially" recognised but it is also extremely controversial.

In my opinion, it is a great flag to highlight the importance of intersectionality within the queer community and useful in its own right, however it should not be used in any way to replace the original rainbow. This is not a huge problem with this specific flag, but it is a problem with the Progress Flag, which this flag set a precedent for.

Another issue is the "officialness" of these changes, which really contrasts to the creation of the original flag. The involvement of a company like Tierney also seems to play into rainbow capitalism, as I believe they were paid to create the flag. It is possible that this flag it was created with good intentions, but it is also possible that it was created performatively to avoid making any real changes.
