Because I am windswept and interesting, I haven’t used Pshop in about 20 years. As a result, I didn’t realise how very…Adobe-like Adobe was being about this EG not just displaying Pantone colours as black, but also REMOVING Pantone information from your existing PSD files when you save them.
Anyway, If you are still being used by Adobe software, you might try the Freetone plugin, which provides you with a palette of colours with code names very, very similar to Pantone codenames. The plugin is free to almost anyone who does not work for Adobe.
