I'm sure the list was comprehensive when Greg Clark first posted it, but now it's out of date. (Nathan is hard to keep up with!) Missing from the list of Eternal inks are Verdun Green and Grizzly (a dark brown). It's
Naval Orange (not Navajo -- and not navel either

). (It's also worth noting that all of the eternal inks, except Black and the ones labeled as Pendemonium or Art Brown exclusives, are Chuck Swisher exclusives.) Also missing is the entire line of Swishmix eternal inks (Nile Ebony, Glacier Blue, Lakeshore Spruce, True Rouge, Burgundy, Tahitian Pearl and Seminole Sepia). No mention of Luxury Blue or the recently announced Luxury Hunter Green. No mention, either, of Blue Ghost or any of the Electric colors (Atlantic Salmon, Sunrise, Firefly, Georgia Peach, Hellfire, Lightning Blue, St. Patty's Eire) (the latter group being non-eternal). Did I mention that Nathan is hard to keep up with?
Greg points out that the "bulletproof" descriptor he assigns to Black, Legal Lapis and Legal Blue is his alone. Nathan's own bulletproof designation is reserved for Black and the two "Luxury" inks (and maybe Blue Ghost -- I can't remember). However, Greg's torture tests are extremely informative, and IMO they may be a better indicator of bulletproofness (in real-world terms) than Nathan's (which seem to be more geared to extreme cases of fraudulent tampering). In any case, if Greg says an ink is bulletproof according to his tests, his conclusion carries a lot of weight in my book.
Hope this helps.
