Text in light background

[GR]

I tried searching the topic before posting this but was unable to find the solution. I am trying to get Calengoo to post dark text in bright background for a particular persion. It happens to be an all-day even, but the text is white istead of black. Thanks.

Look in Settings > Display & use > Général > invert on bright background (below Alldays event font color)
