Picture Elements Card Light Color

Hello guys, I created an Input-Boolean witch turns on the entity oven. Wenn the outside temperature goes below 10 grad celsius, the oven turns on, on my map…

I have done this with candle color in sweet home 3d but in the map, the wrong color (something grey) is shown but not the original fire shining effect.

Do you have any ideas, what can I do tho show the original image?
