Screensaver clock: configurable digit colour (e.g. red at night)

What would you like to addA setting for the colour of the screensaver clock's digits. Today the clock step always draws white on black (hard-coded: CAMERA_PAGE background, CAMERA_INK digits in saver_clock_draw, runtime_tiles.h), and the clock faces (Glass/Classic/Bauhaus) use fixed palette colours too. There is no way to change the digit colour, from the editor, from a Home Assistant entity, or from a plugin manifest option.How this relates to Home AssistantIt would be great if the colour could also be set from Home Assistant, so an automation could colour it by scene or time - for example white during the day and red at night (red preserves night vision best), or amber when an alert is pending. Related: wish 32 (bedroom clock) - Max noted there that "a colour of your own for the digits (set from Home Assistant)" is not in yet; this wish covers the same for the screensaver clock step specifically.If a per-choice colour in the screensaver editor is the simpler route (like the face, look, numerals options in screen_saver.py), that would already cover the night-clock use case; a HA-exposed entity/attribute to override it would be the cherry on top.Use caseA bedside/living-room screen that shows the clock in standby: many people would like red digits at night so the screen stays easy on the eyes and night vision stays intact. Currently only brightness can be lowered - the colour cannot.
