Light Automation

Configuration
1

I have a RGBW light bulb for my patio and I have an automation rule that turns the light blue each night. Most nights it works without any issues but every once in a while the light turns on but goes all white instead of the blue and I can’t figure out why. Any help is greatly appreciated!
