They didn't usually bleach the linen they used, so it had a slight tannish tint to it. Afer it was doped the fabric would yellow in the sun. How yellow it got depended on the original color of the linen, how pure the dope was and whether they tinted the dope. New airplanes with bleached lined could appear be a slightly brownish white, while unbleached linen could be almost yellow, almost brown and anywhere in between. Once this batch gets a little low I plan to start adding one color or another so they aren't all the same. I have some older ones that are quite a bit different from these.
I'm also slowly getting to the point where they started adding color to the dope, and then using colored fabrics.
