Slider Change As Element Trigger

Hi guys,

For many days I can’t figure out how to get this right. What I want to achieve is to trigger different interactions with each slide inside of my slider. (Want my BG element to have a different colour for each slide).

However, even though the interaction is clearly only for the specific slide, in reality, it gets triggered right away before the slide is even displayed. Seems like it simply gets triggered just because the whole slider is in the view.
