Access a specific child inside a vertical box without using Loops, set its color to default before selecting a new one and set it as selected by color.

Hello!

I have 2 widgets, a menu where there is a vertical box and slots widgets that are added to this vertical box through a for loop and these slots have an index associated with each one of them, with each addition. I want to change the color of a slot back to the default before selecting a new slot. How can I access a specific child that has the color, let’s say, already selected (With a yellowish highlight color) inside my vertical box without problems before selecting a new slot with “OnMouseEnter”?

Thanks!
