Hi Tom; Assuming this is the legend ink, Taiyo PSR-4000 is used for ENIG finish here. The Enig goes on first, then the legend, else discoloration occurs. Is the finish gold?

Some of the boards have a distinct purple tint to them. Has anyone seen this phenomenon before? Do you have any ideas what could cause it? Thank you in advance.
