The Elder Scrolls Wiki states that http://static2.wikia.nocookie.net/__cb20131212014730/elderscrolls/images/d/da/Skyrim_oghma_infinium.png "...is made from the skin of the different Elf races: green for Orsimer, tan for Bosmer, dark/cloudy for Falmer, yellow for Altmer and darkest gray for Dunmer. Upon closer inspection, there are in fact six pieces (the tiny dark scrap on the upper left, above the yellow Altmer hide, presumably the skin of a Dwemer)."
Is there any basis, via text or dialogue which supports this claim? I'm specifically curious about the Dwemer skin, but I'd like to see any text which talks about the skin on the cover. http://images.uesp.net/1/16/OB-item-Oghma_Infinium.jpg of the tome looks like it might include some furry beast race hide. And maybe even some Argonian scales. I would like to know if there is any text regarding what the Oghma Infinium is bound with. The colors all seem a little off from the Wiki's interpretation, though I'll grant that they're from dead elves.
I'm looking for quotes rather than speculation, please. I just did the Hermaeus Mora quest in Skyrim and didn't hear any mention of skins. Though obviously there is the gathering of bloods to make the mysterious mixture for the Dwemer blood facsimile. I don't recall any quote from Oblivion either.
Thanks!
