A texture material formulated substantially to match a pre-existing texture pattern. The texture material comprises a carrier, a binder, a filler, and a pH change material. The texture material changes from a wet form to a solidified form when exposed to air. A pH of the texture material changes as the texture material changes from the wet form to the solidified form. An appearance of at least one appearance characteristic of the at least one material forming the pH change material changes as the pH of the texture material changes. An appearance characteristic of the texture material associated with the at least one material forming the pH change material in at least one of the wet form and the solidified form differs from a similar appearance characteristic of the pre-existing texture pattern.
