No, that would be more of a directional selection. Phenotypic change from a minor variant phenotype, black in this case, to the majority phenotype due to the environmental selection pressure of pollution on the moth phenotype.
Industrial melanism is an example of natural selection, where a population's traits change over time due to selective pressures in their environment. In this case, darker-colored moths had a survival advantage in polluted industrial areas, leading to an increase in their frequency within the population.
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
disruptive selection
They both decrease genetic variation
The peppered moth was found to have industrial melanism. This phenomenon occurred during the Industrial Revolution in England, where darker-colored moths were able to camouflage better against polluted, soot-covered tree trunks. As a result, the darker moths had a higher survival rate compared to lighter-colored moths.

When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
