Hi Tina! Are you referring to a specific tubing color name or to the use of white tubing (such as snow white) pumped with Neon gas to make it look pink?
Be aware, if it is the latter, it will eventually shift to a more reddish appearance because straight neon has a UV emission line (maybe near 73nm) that is damaging to the white phosphor...this is why the pinks made that way prove unstable over the long haul.
