Function defined-colors seems to cause the trouble. I stepped down the
code to xw-defined-colors in file ns-win.el. It uses the list x-colors.
It contains only 42 colors.
x-colors is initialized with the return value of ns-list-colors:
(defvar x-colors (ns-list-colors)
What I am wondering about is that ns-list-colors returns a correct list
of 794 colors.
What is wrong with the assignment of (ns-list-colors) to x-colors?
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".)
