Nothing's wrong.  I suspect that some code modifies x-colors after it
is assigned.  Can you see if evaluating the following form

  (defvar my-x-colors (ns-list-colors))

puts the full 794-color list in my-x-colors?  (To evaluate the
expression, put the cursor immediately after the right parenthesis and
type "C-x C-e".)
