The color on the headliner (supposed brown) since I have never owned NOS I cannot comment on. The reproduction color is most surely brown and matches my reproduction seat cover closely (I believe some vendors offer other colors)?

The visors which I have owned NOS are not the same brown as my headliner, they are actually more like the interior paint. However the reproductions (seen in photo) are a match to the headliner.

The RH visor is a fairly rare item and was a dealer furnished accessory, they would install or the customer could.
The armrest was also a similar accessory and this one you can see is definitely brown (I believe Luke/fonz8261 owns this actual NOS one).
