Configure custom button-card to change light color

Hello, I have configured lights in lovelace dashboard using custom button-card. I can change the light or light group color by accessing color-wheel with more-info command. Is there is any way to assign one button-card with single color and clicking on button shall change the color of the light/light-group. In action->call-service/service is not changing the color of the light. Any help is highly appreciated. thanks
