Default plug reading ?'s

NGK, LFR7AIX, been in since getting tuned Feb. of this year, were ran on a very rich, (get me to the tuna), tune for ~two weeks before Feb., (rich enough to foul a new o2 sensor), ran only on e85 since Feb., sz49 plus supporting mods.

Picture was taken with plugs sitting on a white piece of paper which may make the colour seem a bit light. Still, they seem a bit light in colour to me.
If on pump gas I'd think just a bit lean. Look close and you can see they are covered in tiny snow pellets. What is it? What colour should e85 show, light tan, whiter, darker?
