In 3188, during an interrogation, Michael Burnham was asked by the Andorian Ithyk where she had gotten the  gear. The gear was standard Starfleet equipment which Burnham had carried with her from the 23rd century. To the question, she responded that vintage was a matter of perspective. As an example, from her perspective, she said Ithyk was aqua and the Orion Ithor was forest green. ()
