Question on paint color

I'm doing an Austro-Hungarian Phoenix D1 for the Knights of the Sky groupbuild, and I have a question on a paint color.

The kit is from Special Hobby, and it looks like the paints they have listed are Grunze. I know those are Mr. Hobby Aqueous, and the three main colors have the number listed with the color.

The other colors don't have numbers listed, but for the most part, they are obvious. (light grey, brown leather, gloss black and rust)

The issue I have, and the question I have for you more experienced builders is, the last color is just listed as 'cloth'. It's not a major issue, but I don't know what color they are referring to. It's only for the PE seatbelts, so it's not a major color overall. But I'd like to be fairly accurate.

I could just use one of the three main colors listed as it's linen, but if was meant to be the same, they would have labeled it as such. Also, in all the pictures I can find, (very few), it's a lighter shade than the linen.

Just wondering if anyone has any good ideas for a color I could use.
