A cocktail? Yes, Cosmo blue. Turquoise, sweet, tangy, a slice of lemon, an orange zest and Cosmo blue laces.
Very fashionable in hyperspace, only in the hangar or patio of Ground Control (and at the feet of Major Tom). I'm sure David Bowie wore cosmos blue coloured shoelaces when he wrote "Space Oddity", it was the basics. So,inspired by this colour of laces?
