Do you mean flame in no gravity?

You can go to NASA homepage to take a look of flame in space(ship), without the pull of gravitation, the flame is blue in color in sphere. This is because without gravity, there will be no convection, the hot air will not go up but in all direction, the flame burn in the most effective way.
