Methods of producing colored and superhydrophobic surfaces, objects, and coatings using a colored paint that imparts a superhydrophobic surface on an object is a suspension of hydrophobic particles in a polymeric binder and a plasticizer in a solvent or mixed solvent, wherein at least a portion of the hydrophobic particles are colored particles. Colored particles can be ultramarine, iron oxide, chromium oxide, or any other colored metal oxide. The hydrophobic particles can be metal oxide particles that are surface functionalized with a fluorinated alkyl silane or an alkyl silane. The binder is a mixture of PDVF and PMMA in a ratio of 3:1 to 10:1. The plasticizer is a mixture of triethyl phosphate and perfluoro(butyltetrahydrofuran) or other perfluorinated hydrocarbon. Surfaces coated using this paint display contact angles in excess of 150° and resist abrasion.
