Physical change, because no matter what the colour is, its still gasoline.
liquid to gas formation is physical change
Colourless is a property, or word to describe matter, however the "gas" would be something you're describing. However, if a reaction is omitting a colourless gas, it could be considered a physical property of the reaction.
Gasoline evaporation is a physical process.

Gasoline has various chemical properties (particularly, it burns very well) and its combustion products have other chemical properties (they don't burn as well) but it would not be correct to say that gasoline in any sense BECOMES a chemical property. Chemicals have properties, they don't become properties.
