DSP&P Tiffany reefer photo-yellow

This photo was posted, I think, in a 2007 thread, but is now missing.

Has anything new turned up in the last 9 years?

I thought cyanotype photos were all shades of blue, with no other colors. There is also a rock or clothing. that appears about the same yellow, in the upper left edge of the linked photo. If this is a tinted photo, why only yellow? The man standing on the reefer may likely have a white shirt, but it also appears "yellow."

Here is his shirt, copied and pasted over the "A" of Tiffany.
