Describe the bug
The attendee suggestion list is hard to read when using the material you colors in a light theme. Additionally, in light themes without material you colors the suggestion list uses a black background with white text.

To Reproduce
Steps to reproduce the behavior:

1. Make sure the app has the permission to access contacts.
2. Use the material you colors with Android set to light mode.
3. Create a new CalDAV event.
4. Go to the attendee field.
5. Start typing the name of one of your contacts.
6. The contact suggestion list is shown.

Expected behavior
For light themes the suggestion list uses a light background with a font color that provides enough contrast. I'd suggest to simply use a white background and a black font.

I was about to post the same issue for the widget settings ... is it related enough to be handled in this issue or do you want a separate one for it?

@schneidr It's related, no need for a new issue.

I was about to post the same issue for the widget settings ...

I guess for the event list widget the areas marked in red are affected:

left part: dialog shown when tapping on the button "Within the next year"
right part: second dialog shown when selecting the custom option from the first dialog

Correct for the screenshot on the left. The widget itself is working properly for me after setting useful colors.

I have some related enhancements to the Dynamic Color Theme. I've noticed that the colors are much brighter than specified in the Material Design Guidelines. For example, the background color of the FAB is A1-400 in dark mode, but according to the Material Guidelines it should be A1-700. I think it would be more visually pleasing if the Material Design Guidelines were adhered to, also for all other components!
