Does anyone know if the ivory/oyster interior is similar to the ivory/slate? Does the oyster have more brown or gray tones?

 

I had ivory/oyster in my first XF. It is more grey than brown though it has brown in it, it is a beautiful combination and it looked great even with the walnut burl that I usually don't like. Very classy.

 

The interior of my 2009 XKR Portfolio is Ivory/Slate. Click on the the thumbnail to enlarge it.

 

My XK is ivory/slate also, but I can't answer your question about whether the ivory is the same as in your ivory/oyster combo. The jaguar color code for the ivory in mine is NED I believe, though I'm not at home and can't verify.

 

I was looking at a XJ and it was ivory/oyster and the oyster had elements of brown in it. I believe it's usually paired with the gren metallic exterior.
