For example methanol (race car fuel) (1 carbon 4 hydrogens 1 oxygen) burns with an almost invisible flame and acetylene (2 carbons 2 hydrogens (cutting torch without the oxygen turned on) burns with a bright yellow flame with clumps of soot raining down.
A high carbon / hydrogen + oxygen samples will burn with a sooty luminous flame. both luminosity and soot are a result of free (unburnt carbon) As the carbon in the sample decreases relative to hydrogen and/or oxygen soot and luminosity decreases Oxygen content should have a more pronounced effect than hydrogen at reducing soot and luminosity.
