Expandable changes colour after open

Hey Webflow Community,

until now, I managed to solve every problem with answers from the forum. Thanks a lot for the helpful topics!

after the expandable is expanded and “shrunk” again, the colour changes. See pictures.

Question: How can I change the colour after the expand?

  1. before

  1. expanded

  1. after

Thanks and all the best.

Small add-on:
How can the text be aligned? it was once but somehow isn’t anyomre
