In KOrganizer you can select the Holiday Region (in Time & Date), so that Sat, Sun and all [US for me] holidays are shown in red. The panel app Clock will pop-up a Calendar when you click it, but it doesn’t seem tied to KOrganizer? Every day on it is black.
True, the days (numbers) are black on white, but on the top I have Mo.-Fr. in white on blue background and Sa/Su black on white background.
