Hi @pw212 ,
Icon has Color property, I haven't used in Teams App but you can change the color of the Icon as well as its background.
So, if you are using Teams App.
There's a function to get the Theme applied like
//Use the below code for Color property of Icon
Switch(
Teams.Theme.Name,
TeamsTheme.Default,
Color.DimGrey,
TeamsTheme.Dark,
Color.White,
TeamsTheme.Contrast,
Color.Black
)
You can see the output on Teams only, PA editor may not show you the Theme , so run the App on Teams
Adjust color as you like
Hope this helps
