WG is what is used on the Malkoff Surefire drop-ins that aren't warm. Q5, though. I think the modders think WG has gone too green in the R2's, but WG is what was used in the Olight M20 Premiums and is now used in the Nitecore R2 models.
There seems to be a wide range of tints that fall into WG. In Q5 it seemed a bit more predictable.
