I'm ordering some illuminated door sills not sure which interior I have (pretty sure its tan?)

Please help don't want to order the wrong sills .

Which option do I pick?

I would say cashmere. Ecru is more white. Matter of fact I thought it WAS white.

Here are the color options for 2007 350

I think Ecru is on 09+

Mine Is Blue, is that normal?

I have the exact two tone like yours, I ordered the black floor mats to replace the tan ones which get dirty way too easily and went with the black illuminated door sills with blue leds, they turn out great, at least to me.

The light colored interior is Cashmere for 06-08 and Ecru for 09+

Blue was the color for the light of the scuff plates on 06-07, they changed it to the (IMHO nicer looking) white in 08
