I never had any luck changing the color settings in xlights prior to this year. In the past, I manually manged my controller settings and always changed this setting at the controller level. This year I am letting xlights manage the controllers. If I change the color settings in xlights now, it will change the color settings on the controller. I could not find in the manual what that setting does, but I wonder if that setting only applies when xlights is managing the controller.
With that said, if xlights is managing your controllers, make sure to upload the new configuration to the controller. If you are managing the controllers manually, I would suggest to make the color change at the controller level instead.
