SetUiPaintColorSettings is not effective

Hi;

It works in Rhino 7.0, but not in Rhino 8.0.
Is it that my method is incorrect?
SDK version:8.0 SR12

Here is the code:

CRhinoUiPaintColorSettings ui_setting = RhinoApp().AppSettings().UiPaintColorSettings();
ui_setting.m_normal_start = ON_Color(234, 236, 240);
ui_setting.m_normal_end = ON_Color(234, 236, 240);
ui_setting.m_normal_border = ON_Color(234, 236, 240);
 RhinoApp().AppSettings().SetUiPaintColorSettings(ui_setting);

Hi @147026546,

What UI elements are you trying to colorize? A screen capture might help.

Thanks,
