Hmmm, not sure. Gold clear is a contrast lens, sure, but it's subtle - I'm not sure a couple of microns of iridium could so thoroughly overwhelm a couple of mm of coloured lens base.
Held up to a light source and looked directly through, violet appears to be the same base as fire. Ruby does look to have a blue base compared to the likes of black and emerald, but, as it doesn't enhance any contrast, Oakley lumps it in with the true neutral greys.
