Update, October 8, 2019 (3:15AM ET): We’ve been waiting for the Colorize feature to land in Google Photos for over a year now, promising to bring AI-generated color to monochrome pictures. Thankfully, it looks like we’re a step closer to the feature rolling out for all users.
9to5Google obtained version 4.26 of the Google Photos app and managed to enable a beta version of the Colorize feature. The outlet noted that the Colorize option will appear after the Original and Auto filter options when editing snaps, complete with a beta tag.
