A surface is masked or stenciled off in a specific pattern or design and treated with a liquid or vapor chemical composition. The resulting pattern or design on the surface is substantially invisible in the absence of condensation. As the surface is subject to a temperature change, for example, moved from a cooler ambient to a warmer ambient, the specific pattern or design becomes visible as a result of selective condensation.
