Google Home Bug Prevents Color Changes on Smart Lights

Google says a fix is rolling out, leaving owners to use each bulb maker’s app to change colors until the update reaches their devices.

Overview

Users first flagged the problem on Reddit and tech sites after finding the Google Home app and voice commands would not change bulb colors even though the color picker still appeared.
Affected devices kept working for simple power and brightness controls, but color sliders did nothing except sometimes allow white or yellow tones.
Reports show the fault crossed multiple brands, including Philips Hue and Tuya-based bulbs, which points to a platform-side regression rather than a hardware failure.
Google responded to the Reddit thread saying a fix was rolling out and the original poster later reported that color control returned for them.
In the meantime homeowners who rely on color-based routines must open each manufacturer’s app to set colors, and users should watch for Google’s public update or a full rollout before normal automation resumes.
