A normal candle flame on Zero Gravity

A normal candle flame on Zero Gravity is round and blue in color.Also it isn't true that candles burn for a shorter length of time in space. Dr. Shannon Lucid (Mir), found that candles that burn for 10 minutes or less on Earth produced a flame for up to 45 minutes. When the flame is extinguished, a white ball surrounding the candle tip remains, which may be a fog of flammable wax vapor.
