In ELISP manual, info about color-values is not true any more with NS
port merged.
,----[ (info "(elisp)Color Names") ]
| -- Function: color-values color &optional frame
| This function returns a value that describes what COLOR should
| ideally look like on FRAME. If COLOR is defined, the value is a
| list of three integers, which give the amount of red, the amount
| of green, and the amount of blue. Each integer ranges in
| principle from 0 to 65535, but some displays may not use the full
| range. This three-element list is called the "rgb values" of the
| color.
|
| If COLOR is not defined, the value is `nil'.
|
| (color-values "black")
| => (0 0 0)
| (color-values "white")
| => (65280 65280 65280)
| (color-values "red")
| => (65280 0 0)
| (color-values "pink")
| => (65280 49152 51968)
| (color-values "hungry")
| => nil
`----
It says return value is (R G B).
In NS port, color-values uses function xw-color-values:
,----[ C-h f xw-color-values RET ]
| xw-color-values is a built-in function in `nsfns.m'.
|
| (xw-color-values color &optional frame)
|
| Return a description of the color named color.
| The value is a list of integer RGBA values--(RED GREEN BLUE ALPHA).
| These values appear to range from 0 to 65280; white is (65280 65280 65280 0).
| The optional argument frame is currently ignored.

`----
The return value is (R G B Alpha).
So the info manual need be revised.
