Those 3D models are great, JB- it would be a neat side job to create designs for video games or some such.  I completely agree on how Angel and Beast's outfits would reflect light, as two different materials of black color (though I believe Angel, like Cyclops, has been more commonly accepted as wearing blue rather than black- even if the original intention was to wear black).  With more reference of how you have Beast colored in that one scene, I think the argument could be made that he's wearing dark grey (the way the modern Black Panther is depicted), but it definitely could be black and the environmental light is subtle.

I really don't think Angel's boots were considered blue, but perhaps they were colored with the same idea behind coloring black hair: not true to life, but more interesting with some color within.  Anyhow, like someone mentioned, it isn't of vast importance, but rather what it means to each of us (someone telling me Cyclops' outfit is black is like me seeing a modern interview with George Lucas saying that the Special Editions are how he always intended the trilogy to be- he may be the creator of it, but even he can't dispel 30 years of what I saw :-). It would be interesting to hear the opinions of long-time and modern colorists or painters of comics about the colors of key characters.  If someone like Alex Ross paints Cyclops as blue (not needing to fill in highlight areas as with inked artwork) can we assume he thinks it's blue?  What about action figures or statues in which there is no black at all?

Ross seems to think the Flash's costume is Spandex. Does that make if Spandex? (I wonder where he buys Spandex that can be compressed into a ring compartment smaller than a dime?)

I may be crazy, but that yellow and brown Iron Fist costume looks so much more appealing to me. I can't explain it.

Well, I don't mean that Ross is the authority on everything, just citing an example of someone who may believe Angel and Cyclops have blue outfits since he isn't limited by the coloring options that classic comics were.  (By the way, I hope I don't give the impression of being absolutely correct and won't hear dissenting opinions or fact; it's just that I was truly surprised to read about Cyclops and Angel, and that was the first time I had ever read that).

The last couple of days I've been looking through OHOTMU and other comics, and there seem to be more layers to this than I realized.  I believe that there are instances where most images of a character are highlighted with blue, yet the outfit is not meant to be blue, such as Spider-Man's black outfit.  Occasionally the New Mutants' uniforms are highlighted with blue, but are not blue (as far as I believe it).  Then there are characters like modern Black Panther and Miller-era Black Widow that have the vast majority of their surface area in grey.  I'm wearing a soft cotton black shirt right now, and where the room light is landing, it certainly appears greyish.  So Black Widow could be black if enough light is striking her at most times we see her, but then that leaves the problem of the widow symbol on her chest (see below). 

Cannonball as I believe his costume to be:

Cannonball as he sometimes is highlighted (is his uniform really blue, or is he the only one on the cover illuminated by blue light?  More likely he is highlighted not true-to-life)

Black Widow- grey outfit (if she is considered black, then what color is the spider symbol on her chest?)

Then we have Spidey- I would think everyone considers this a black outfit, not blue, yet he has the blue highlights.  Since so much of him is always covered in shadow (as opposed to Cyclops or Angel who are often more brightly "lit") I think it's easier to call this suit black.  But again it's probably similar to the coloring of black hair with blue highlights tradition (though I seem to recall modern Spidey comics' "back in black" storyline having him depicted without blue?  I can't remember EDIT: I found a modern Spidey pic, placed below this one, and it seems to support that it is black, not blue.

Lastly, an Angel bust.  Is this incorrect to you, JB?  I just see it as a blue uniform that creates its own shadows in black based on the lighting around it (there are some black areas on this bust created by lack of lighting rather than being painted that way)

i never really gave the actual colours much thought, they are the colour they were on the printed page that was good enough for me.

now im wondering,Captain America, blue or black?
