      I know if you add certain elemental salts to fire you can get a purple flame. But I’m not sure if there is a specific gas that would give a purple colour. In glass chemistry, manganese will make a glass turn purple, but I don’t know if it will make something burn with a purple flame… I think the colour of fire also has a lot to do with the temperature and pressures involved too…

      The colour of stars is normally linked to their temperature, so a purple star would be really hot as purple light is higher energy than orange light like our sun gives out. A purple star would probably be bigger and it could make different elements to the sun because it has more energy, so it might contain uranium and other heavy metals but would be mostly hydrogen and helium

      Stars are not burning as such but they are giant nuclear reactors relying on nuclear fusion (fusion of hydrogen) to provide their power, I guess it could appear purple if the atmosphere was polluted somehow, or wearing purple tinted glasses!
