Google Home users have reported that their devices are no longer able to change the color of connected light bulbs from several brands, including Philips Hue. According to Android Authority, many users discovered this issue on Tuesday, though the lighting and brightness functions of the bulbs still worked normally. The problem seems to be linked to a software bug affecting the Google Home app, voice commands, and automation routines. Users shared their experiences on the Google Home subreddit, confirming that they could no longer change the color of their lights through the app, via voice commands using Google Home Speakers, or through a Google Nest Hub screen. Routines designed to alter the color of the lights were also impacted. A dozen users confirmed the issue, and a journalist from Android Authority tested it on Tuesday morning using Philips Hue bulbs, finding that neither the Google Home app nor connected speakers could change the color. The issue affects multiple bulb manufacturers, but only the color-changing functionality is malfunctioning. Turning the lights on, off, and adjusting brightness still works through Google Home. A temporary workaround exists: users can still change the color using the manufacturer’s app, which suggests the problem lies with Google Home rather than the bulbs themselves. Google has not yet acknowledged the issue or announced a fix. This is the latest in a series of color-related glitches. In April 2026, a similar issue affected the interface, causing it to lose color commands on certain bulbs, leaving only a few shades of white. At the time, a workaround using the manufacturer’s app was available, and Google announced in early May that it had resolved the problem. Current reports do not specify any particular region, so it remains unclear whether France is affected. Until a fix is available, users are advised to use the manufacturer’s app—such as Hue, WiZ, Tapo, or others—to change colors and to check if any Google Home scenarios relying on color are impacted. The issue highlights the ongoing challenges with smart home devices and the reliance on software updates to maintain full functionality.
