The Free On-line Dictionary of Computing (30 December 2018):

Taligent

   A company founded jointly by Apple and IBM in March 1992.  HP
   announced in January, 1994 that it would buy a 15% stake in
   Taligent.  They are working on an "object-oriented operating
   system", due to be finished sometime in 1995.  However,
   various independent pieces of Taligent will likely appear to
   be used with other operating systems, e.g. IBM's WorkplaceOS.
   Pink is an older name for Taligent, dating back to work that
   Apple did before the formation of Taligent.
