PROBLEM TO BE SOLVED: To provide an optical article having an easily colorable nature, a manufacturing method of the optical article, a colored article obtained by coloring the optical article and a manufacturing method of the colored article.

SOLUTION: The optical article has a reflection prevention layer on a substrate and is equipped with a photosensitive layer capable of developing color by a developing solution between the substrate and the reflection prevention layer. The reflection prevention layer is constituted so that the developing solution can permeate as far as the photosensitive layer. The manufacturing method of the colored article comprises a photosensitization step of photosensitizing the photosensitive layer by irradiating the optical article with light and a color developing step of color-developing the photosensitive layer by the developing solution.
