How can the outline of the text on a button be changed when the mouse hovers over it?

I noticed this might be a limitation. I am playing around with themes at the moment and I managed to change the font color for accel, disabled, hover and normal. Under fonts I can set the size and outline color but there is no option for hover vs normal.

I see this is an old question, but if anybody stumbles upon it, this is how I solved it:

Add the script below to the button

extends Button

var custom_font = get("custom_fonts/font")

func _process(_delta):
	if is_hovered():
		custom_font.outline_color =
		custom_font.outline_color =

For this to work for the button, don’t forget to add in the Inspector under Control / Theme Overrides / Fonts / Font a DynamicFont and set the Outline Size to your liking.
