Provided are ink compositions, methods for making photochromic inks, and methods of using the photochromic inks for erasable media annotation. In accordance with various embodiments, there is an ink composition including a carrier medium and one or more photochromic species in the carrier medium, wherein each of the one or more photochromic species can be selected from the group consisting of monomeric photochromic molecules, photochromic oligomers, and photochromic polymers, and wherein each one of the one or more photochromic species exhibits a reversible transition from a colorless state to a colored state upon exposure to a radiant condition wherein the radiant condition can be selected from the group consisting of a radiant energy and a combination of a radiant energy and thermal energy.
