I think it may be blue. Of course, I'm not sure, but it seems to make sense from what I found:
Color Coding Surgical Margins with
The Davidson Marking System
Anthony V. Parkinson*, C. Ron Cannon, and Steven T. Hayne*
Department of Pathology
Rankin General Hospital
Multiple colors allow identification of five surgical margins rather than just three, two short axis margins, the two long axis margins, and the deep margin. Evaluation of the five surgical margins can identify the specific site of an existing tumor and its probable extent beyond the surgical margin of resection for the attending surgeon. Re-excision of the involved margin can then be performed. The most commonly
employed dyes used for the marking of a surgical margin have included merbromin (red), common laundry
bluing (blue), and India ink (black), which were not designed specifically to withstand frozen section tissue processing or routine processing of tissue (2). No other commercial system is available. Recently, dyes
specifically designed to withstand immersion in high concentrations of alcohol and xylene and to remain
affixed to the tissue have been developed.
