I have tried to tackle this issue multiple times, however due to how the color system works on Windows, I have had troubles getting this to work properly. If I change the text color to black on bright accent color, then I would also have to change it not only on the events, but also on the tags and then also on the colored header of the app window - otherwise it would all look inconsistent. And every time I tried to do this, I failed. Another problem is that the app uses 2 different accent color shades. A brighter and a darker accent color. When a dark text color would make sense on the brighter of the text colors, it might look off on the darker on. For example here:
It's not trivial unfortunately... WorkingHours doesnt have that colored header and therefore this problem doesn't exist in WorkingHours.
