Mike is probably right as I couldn't find anything about different colors or blends. I did find this, if it helps:
Coleman Fuel (naphtha or “white gas” as it’s also called), was developed in the early 1950’s as small motor fuel for lawnmowers, outboard motors as well as an industrial cleaning agent.
So what is Coleman Fuel made of? In its simplest form it's a petroleum product either derived from natural gas or distilled from oil, coal tar or peat (partially decayed vegetation matter) due to its high carbon content. It also has a several other chemicals mixed in which include cyclohexane, nonane, octane, heptane, and pentane.
Coleman Fuel is ideal for small stoves and lanterns due to its refined purity and high heat output. It also doesn’t give off the black smoke and toxic fumes that regular gasoline or kerosene does.
Though it’s almost as flammable as gasoline, don’t put it in your car’s tank as the lack of some additives will cause engine knocking and eventually destroy your engine valves. An un-opened container of Coleman Fuel stored in a dry area with no rapid extreme changes in temperature will remain viable for five to seven years. An opened container stored in the same area will remain viable for up to two years though will be at its best if used within a year.
