Reggie Bullock had a colorful idea for the NBA this past Sunday.

The Detroit Pistons player and advocate for the LGBT community tweeted at the league to allow for rainbow-colored jerseys, according to PinkNews. Bullock is not gay, but is an ally to the community.

โ€œJust woke up out a dream and thought about playing in a ๐ŸŒˆ colored jersey to incorporate #LGBTQ into sports,โ€ Bullock tweeted. โ€œ@nba help me make it happen in my lifetime ๐Ÿ™Œ๐Ÿพโ€

Bullock previously got involved with LGBT activism after his transgender sister Tia Henderson was murdered in 2014, according to PinkNews. Besides having his sisterโ€™s name and LGBTQ tattoed on his body, he has also hosted events with GLAAD and Athlete Ally.

The NBA has previously worked with LGBT charities on several different projects. When Jason Collins came out in 2013 as the first gay player in the NBA, the league reportedly donated the proceeds from his jersey sales to Matthew Shepard Foundation and the Gay, Lesbian & Straight Education Network (GLSEN).

The NBA teamed up with GLSEN in 2016 to sell Pride Month t-shirts on online retail website Fanatics, according to PinkNews. They also partnered with the National Gay & Lesbian Chamber of Commerce in 2017 to allow for more opportunities for LGBT businesses to get involved with the league.
