Need help with adding border color to visual novel textbox made using Dialogic plugin

[maiden void]

It's strange. I can change the position of texts inside, but I can't change its color and add border color.

The color remains black.

And there's no white border.

Can someone help me?

Could that panel be being hidden by the other Control nodes it has as children?

How do I check that? Sorry, I'm new to this.

Well, if its children are just as big, they are going to be drawn above it.
In that case you have to change the theme of those children. Whichever is the one being drawn on top.
