Despite what Lexol might say, I've found that Lexol NF does in fact change the color of leather, though slightly. Last night, I put on a light coat of NF on a new A2000 (thanks John!). The glove was the typical Wilson flesh-colored leather. Now it's more of a light caramel / tan. Don't get me wrong, I love how it "mellowed" the color (which is exactly what it says it'd do on the back of the bottle).
On the other hand, I also used it on that old Ted Williams 400 that I picked up over the weekend, which was very dry, and a VERY light colored glove - bordering on light grey. Though the NF did very slightly darken the glove, it wasn't nearly as dramatic as the results I got with the A2000 - the lighting is different in the pics, but trust me, there's a noticeable difference.
Keep in mind that I wanted these changes, and that all of the darker gloves I've used it on, there was absolutely no change. I guess my point is - be really careful before you use it on light gloves (unless you want a slight change in color).
