Have you seen the new Leave No Trace Trainer and Webmaster leadership position patches? I mean actually looked at the real patch? Here's an image for another look, along with a standard patch.

These are to be worn by scouts in these positions of responsibility. In that context, I would expect the patches to follow the same color scheme and style as all the other position patches.
It would seem weird to have a couple patches different than the other 15 positions. But, the lettering color is black on the Webmaster patch and light green on the LNT Trainer patch. And, the font is different on the patches, too.

It almost seems like the BSA patch people grabbed a patch that was already created. Either that, or the design review was lacking. Or, these patches are the first of a new 'Centennial' version of the position patches. Well, it's possible.
