RE: Annodized Al Ally
There are a variety of dyes that you can choose from.

I guess I left out the most important part: "Clear / No Dye" There is a small arguement going on in here that it the type 2 class 2 greys the metal. Is that true?
RE: Annodized Al Ally
I seem to recall that this finish would tend to have a light mottled gray coloration with a "semi-gloss" to "flat" luster... depending whether it was hot-water sealed, or not.
Also... At an angle, and/or with polarized light (including sunlight) the appearance may also have a slight holographic translucence.

Type II is sulfuric acid anodizing, conventional coating produced from sulfuric acid bath.
Class II is dyed
I would take this to mean you can not have "Non-Dyed" and still be class II.
Class I is non-dyed.
It goes on to say on class I that any coloration resulting from anodic treatment with various alloy compositions shall not be considered coloration. The charistic color imparted by the sealing process shall also be considered non-dyed.
I believe this spec goes on to describe quality inspection of parts.
RE: Annodized Al Ally
Your assessment is correct.. Wes616 is actually describing non-dyed sulfuric acid anodized coating per MIL-A-8625 Type II Class 1.
