Crayon
A crayon was a tool used for drawing, especially by young children. One of the colors available was royal blue.

In 2369, a de-aged Ro Laren drew a picture of her mother with crayons. Guinan remarked to her that the wonderful thing about crayons was that they could take you to more places than a starship could. ()

In 2380, Ensign Beckett Mariner and Bradward Boimler were handing out crayons and other art supplies to Betan children on the streets of Beta III. ()
