An albino was anyone whose skin pigmentation and eye color was lacking. This trait appeared among such species as Humans and Klingons. (TNG: "Time's Arrow, Part II"; Star Trek VI: The Undiscovered Country; DS9: "Blood Oath"; DIS: "Battle at the Binary Stars")
In the 23rd century, albinos were not commonly accepted among the Klingon society. Voq was an albino Klingon who was outcast from his Great House, but accepted by T'Kuvma in the House of T'Kuvma. Voq eventually conceived a child with future Chancellor of the Klingon High Council L'Rell, which was also an albino. (DIS: "Battle at the Binary Stars", "Point of Light")
