Abstract: Temporary marking compositions for producing colors upon contact with a surface, especially one covered in snow or ice, are disclosed. The compositions contain a water-soluble salt or a mixture of water-soluble salts, one or more colorants and water. The compositions may include a stabilizer, an extender, additional antifreezes, surfactants or emulsifiers, anti-bacterial/anti-fungus agents, flourescents and other ingredients. The compositions may contain only antifreezes such as alcohol, glycerol and propylene glycol, polyol fatty acid esters, their derivatives, or combinations of the salts and/or the other antifreezes. The methods of marking are disclosed.
