Colored-noise-induced anomalous transport phenomena of overdamped particles in a tilted periodic sawtooth potential driven by a nonequilibrium three-level noise and an additive thermal noise are considered analytically. All the physical results discussed are computed by means of exact formulas. It is demonstrated that the particles exhibit anomalous transport properties, such as, multiple change in the sign of the particle flow, absolute negative mobility, negative differential mobility, hypersensitive transport, and hypersensitive differential response. The necessary conditions for various anomalous transport properties are found. It is established that in certain parameter regions an increase in noise parameters (noise-flatness, correlation time, temperature) can facilitate the conversion of noise energy into mechanical work - i.e., the dependence of the efficiency of energy transformation on noise parameters exhibits a bellshaped (resonance) form. Some possible applications to fluctuation-induced separation of particles as well as to the amplification of small signals are also discussed. Our results provide some new perspectives to support elaboration of a model of interaction between plasma beams and construction materials in plasma focus devices.
