Zack Snyder's Justice League will be getting a black and white version though it's unclear when and where that version will debut. The Snyder cut of Justice League, the redone version of the 2017 film directed by Joss Whedon, is set for release on March 18. 

In an interview with Minutemen, Snyder confirmed the existence of a Black and White version titled Justice Is Gray. He said, "Right now, we're finishing the black and white version of Justice League. It's called the Justice Is Gray edition. That's what I call it."

It is speculated that HBO Max, the streaming partner for the full-coloured version, might grab the other version too. 

While Snyder was roped in to direct the 2017 film, a personal tragedy forced him to opt out of the project. Whedon took over the project and the film opened to mixed reviews. After years of online campaign, HBO Max got Snyder on board to finish his version of the film, which was reshot with an eight-figure budget.
