TL;DR
Google Home was having problems with some users’ RGB lights in April.
The Home app could control light brightness, but not color.
Google says these issues have been resolved.
Last month, Google Home users reported an annoying bug around RGB smart lights, with the Home app still showing on-off and dimming controls, but no options to change light color. There was an unofficial workaround, but it was kind of a hassle. Google says it’s fixed the issue, however.
The issue only ever affected some users, with others reporting Google Home never missed a beat when it comes to controlling their smart lights. Still, multiple users took to say that their color-controllable lights in Home only showed options for a handful of different shades of white.
