What is your interior color code? (From the drivers side door panel?) If you punch that code into google, does it give you a name?
Mine was weird. My seats and dash on my 07 are this light grey looking color. I punched in the color code to get a new dash insert, and mine said "Khaki". Hmmmm.... I wore "Khaki" almost every day of the week for my last 6 years in the Navy, and my interior was nowhere even close to that color! But I ordered the Khaki dash insert and it matched perfectly. Odd.
It's the same on that link you posted. "Khaki" on their color chart looks light grey to me. The color they call "Sandstone" is closer to what I would have called Khaki. That is the color that matched my Khaki uniform.
All the best,
