Appointment text, color and size

I have been trying to display the next appointment for some time. I would like to give it a different color, e.g. red and size 55.
I have tried it as a small and large box. In the preview (in WFS) it is displayed correctly. On the clock
the color and size do not change.
If I make it as a text box, I can change the size and color, but a maximum of 9 letters are displayed as appointment text.
Does anyone know a solution?

If you are using any complication keep in mind the layout may change based on the complication provider.
So if you change any component properties of a complication please keep a single layout that is appropriate for the complication and delete others layouts. Or you may change all the layout properties individually.
