In 2021, Valentino Vecchietti of Intersex Equality Rights UK, adapted the design of the Progress Pride flag to incorporate the intersex flag, creating this Intersex-Inclusive Pride flag, posting it via Twitter and Instagram. It includes a yellow triangle and a purple circle, to reflect the intersex community, and was adopted as the new pride flag after going viral on the internet. This flag appeared at the 27th Copacabana Pride Parade.

The flag has also been used by companies and entities such as Microsoft and the São Paulo Museum of Art. Wikipedia
