The present invention is related to reactive dyes each of which comprises a dichlorotriazine or chlorotriazine group and has a desired UV/visible absorption spectrum for selectively filtering a certain color light. They are suitable for method for producing colored silicone hydrogel contact lenses each made of a silicone hydrogel material having hydroxyl groups. The present invention is also related to a colored silicone hydrogel contact lens comprising a colored annular ring and/or a colored circular area in which a reactive dye is applied and thereby covalently attached.
