Watch face dosn't work

Hello, I’m new here in the forum and I think the possibilities with Facer Cretor to design a Watch Face to be good. Now I have a problem with a self-designed watchface. With the watchface the complete color design should change at the time of the sunrise and the sunset. In the simulation mode of the “facer creator” it works. If the design is transferred to my HUAWEI Watch2, it will not work. I created the design on a Macbook Air (Mojave 10.14.3) in the Chome browser. My HUAWEI watch has the newest WEAR OS. Can somebody give me a tip with that? Thank you.
Please excuse my not so good english.
