Light Card icon does not change color when toggled on

Hello,

Hopefully I overlooked something simple but, I cannot get the icon (receptacle or light bulb) of the light card to change color when toggled on. The slider will change color if the lights are dimmers but not the icon itself. I’m using the midnight theme but have tried others with the same result. Any ideas are welcomed.

I did add state_color = true, in the yaml section but there was no change.
Thanks .
