A candle with a colored flame is described, which is free of the yellow color, usually found in the conventional paraffin candle. The candle comprises (1) a shell made of a saturated thermoplastic material and 10-30% of a fire retardant: (2) a fuel consisting of 70-100% of a polyoxymethylene, 0-30% of a binder, and 0-20% of a solvent. The candle also comprises 1-10% of a flame-coloring agent, such as a salt or an oxide of Li, B, Na, Ca, Cu, K, Sr, In, or Ba. The candle does not require a wick.
