Ah, apologies. [He coughed, again very uncomfortably.] There is a complication in our culture in romantic liaisons. While some shifting of the hemospectrum is expected, drastic ones come with explicitly negative connotations it behooves trolls to remember.

I have a somewhat shameful taste for the rust-blooded and red-blooded varieties of our species. It at times makes potential liaisons with humans both appealing and a little... problematic. The color of your blood is that of our lowest castes, though I accept that your species is not as we are in this.
