Settings where candles provide the majority of ambient light. This makes for dark scenes with amber-colored light radiating out from the candles themselves.
This tag is not to be used when there's merely a lit candle in the image. It needs to be a dark setting illuminated by the light given off by at least one candle.
Correct examples
The candle is the main light source of what is otherwise a dark setting
Birthday cake's candle is creating a warm, amber glow
Incorrect examples
The candle is merely lit
The main light source is from the window, not the candles on the birthday cake
