Help creating color theme

Here is the thing. I want to create a sequence of lights changing to 3 specific colors when my son’s team wins a game :wink: I created a widget in IFTTT but not sure what the syntax should be. Any help ?

This is what I wrote :
color: #FF0000;brightness: 1;transition_duration: 2.5;color: #FFFFFF;brightness: 1;transition_duration: 2.5;color: #FF0000;brightness: 1;#FFCC00;


Unfortunately our IFTTT integration doesn’t have the ability to perform more than one action per request.
