Is the color of any item's text (aside from white text and Rares) different due to the presence of Sockets or Etherealness, whether the Sockets were created or existed upon drop?

Non-magical (low-quality, normal-quality, or superior-quality) items have a grey text if they're ethereal or if they have sockets (regardless of where the sockets come from). Otherwise, they're white-text.

Only non-magical items have this distinction. Magic is always blue, rare is always yellow, crafted is always orange, unique is always gold, set is always green.

(Can an item be made Ethereal?)

No.
