Nope, after quite some testing it seems to be the BoldFont etc. keys that are broken.

Take the following minimal file:

\documentclass[12pt]{article}
\usepackage[dvipsnames]{xcolor}
\usepackage{fontspec}
\setlength{\parindent}{0pt}
\begin{document}
\defaultfontfeatures[texgyreadventor-regular.otf]
  {
   Color=Blue,   
%   BoldFont=texgyreadventor-bold.otf
  }
\setmainfont{texgyreadventor-regular.otf}
Roman text.\par
\textbf{Bold text}\par
\textit{Italic text.}\par
\textbf{\textit{Bold italic text.}}
\end{document}

This typesets fine, and in blue as expected, except for the absence of bold and italic. Uncomment the line specifying the bold font, you'll get

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!
./Last-Test.tex:11: LaTeX error: "kernel/key-unknown"
! 
! The key 'fontspec/BoldFont' is unknown and is being ignored.
! 
! See the LaTeX3 documentation for further information.
! 
! For immediate help type H <return>.
!............................................... 

Searching fontspec-{luatex,xetex}.sty, it turns out the two keys are implemented in different ways:

\__fontspec_keys_define_code:nnn {fontspec-preparse-external} {BoldFont}

\__fontspec_keys_define_code:nnn {fontspec} {Color}

This might indicate there is something wrong with fontspec-preparse-external.

I will try to look for a mailing list where fontspec issues can be reported, since this is clearly not a Lucida-specific problem.
