since frontend themes added, temp sensors on floor plan (picture-elements card) are nearly invisible. How can I get them back/black/darker? :slight_smile:

I have tried as per the doco

"--paper-item-icon-color": black

and this seems to influence nothing

ok, apparently; Picture-Element card Icon color not working anymore

it only works in the state-icon element type

is there a way I can bolden the font?
