[Bug]: Icons to indicate objects in the Events review screen are hard to see in Light mode

[supermarkert]

Describe the problem you are having

The icons for object detection are white, on a very light gray background. With so little contrast, it's very difficult to see (especially on a larger screen when the icons are so small).
Suggest using a darker color against the background using a color similar (but different) from the timestamp.
This is only an issue in Light mode. Dark mode can be viewed fine.
