change color of widget icon

Hello,
the color of the arrow symbol for scrolling further in a widget cannot be changed. At first, the arrow wasn’t visible either. Then I changed the settings and now the arrow is visible. But the blue just doesn’t fit in the shop. I am grateful for any help. I’ve been looking for a solution for hours. It looks like the arrow is not used by my theme. That’s some kind of take on Elementor that I can’t find.
Thank you.
