For the Lamina B.L.A.C.K I wanted to use orange colored nixie tubes, like the ZM1210. I ordered some glass lacquer for light bulbs in orange and red colors than I mixed them until I had a desired color and dipped them to paint. For each B.L.A.C.K clock I need 6 nixies, plus I send 2 spare to the customers to have the matching color spare in case it is needed.
