There is a perfect ratio of fuel to air that is perfect. For example, 2 parts fuel to one part air. If you stray from that perfect mixture, you'll have different flame properties

It is. Hotter more complete gas fires are blue. "colder" less complete gas fires are orange.

Essentially, impurities, the material being burned, and uneven combustion. A clean hydrogen flame is almost invisible. When burning a propane flame it is blue and purple when it has good even combustion and ionizes the gasses in the flame and it turns blue. Orange flames are more uneven combustion as well as different fuel being burned.
