Question

I tried to change the colors of a button via “add_theme_color_override()”.
But the colors doesn’t change.
The Button has a Theme attached and in the inspector window, the style override’s are empty.

Script:

func _on_Size_button_focus(SizeMenu_button: Button):
	
	# override colors
	var size_button = $Menus/HBoxContainer/VBoxContainer/SizeOptionButtonContainer/SizeOptionButton
	var focus_color = GlobalOptions.menu_canvas_color_focus
	var normal_color = GlobalOptions.menu_canvas_color_focus
	size_button.add_theme_color_override("focus", focus_color)
	size_button.add_theme_color_override("normal", normal_color)
	print(size_button.get_theme_color("focus"))  # Sollte focus_color ausgeben
	print(size_button.get_theme_color("normal"))  # Sollte normal_color ausgeben

Global Variable:

var menu_canvas_color_focus: Color = Color(0.004, 0.18, 0.251, 1.0) # #012E40

print shows:

(0.004, 0.18, 0.251, 1)
(0.004, 0.18, 0.251, 1)

The Print shows the right Color, but there is no visual change ingame.
What did i do wrong?

Okay, i solved it…
Script:

func _on_Size_button_focus(SizeMenu_button: Button):

	# override colors
	var size_button = $Menus/HBoxContainer/VBoxContainer/SizeOptionButtonContainer/SizeOptionButton
	var new_style = StyleBoxFlat.new()
	new_style.bg_color = GlobalOptions.menu_canvas_color_focus
	size_button.add_theme_stylebox_override("normal", new_style)
	size_button.add_theme_stylebox_override("hover", new_style)

Global Variable:
var menu_canvas_color_focus: Color = Color8(1, 46, 64, 255) # #012E40
