description Writing compositions capable of undergoing a color development when brought into contact with a specific substrate including a color change-inducing compound are provided. Writing instruments comprising such writing compositions are also provided. Application of the writing compositions to surfaces other than the intended substrate will avoid color development and prevent staining of the unintended surfaces. The writing compositions include at least one mineral filler, at least one leuco dye, one or more lipids including one or more waxes, one or more fatty acids, or one or more fatty acid esters or fatty amides, titanium dioxide, and optionally at least one additive.
