Abstract
Methods for spot-dyeing a damaged area on a textile employing a selected color loss filter and utilizing at least one of a primary color dye. In one embodiment, the method can include the following: inspecting the damaged area through the selected color loss filter; determining whether a primary color is missing from the damaged area by being able to view the damaged area through the selected color loss filter to, thereby, confirm that the primary color is missing from the damaged area; and applying at least one of a primary color dye, corresponding to the selected color loss filter, to the damaged area, while viewing the damaged area through the color loss filter, until the damaged area is substantially invisible through the color loss filter.
