Haven't read the whole thread, so sorry if this is a repeat... TransBlack... that's as in Transparent and not transitioning (from Charcoal?).
Yes, that's the only way I've ever seen "Trans." used in Guild's color naming, but most of my source material's from the '90's.
On the other hand, I think if it was a "transition effect" they'd just call it a "burst", like the oddball D4 we saw with a "Silver Burst" a while back:

Definitely "outside the envelope".
And in fact on my new LCD monitor it looks just about as brown as Grot's Pilot; hardly "Silver" at all, except for the pickguard.
The first time I saw it a few years back on a traditional CRT monitor (and obsolescent video card) it
did look more silver/gray.
Further complicating things is that it looks like the same pigments may have been given different names at different periods.
:eek-new:
Now that I read the rest of the posts, I see this HAS become a color discussion!. Absolutely would benefit from direct sunlight. You may also want to make sure your "Camera" is set correctly, even most phones have a "White Balance" sometimes simply choices between indoor/outdoor or incandescent/fluorescent/sunlight/candlelight/etc. And of course, as I mentioned "Pretty Wood", Maple will take the color differently than other woods like poplar or mahogany.
Also a very good note, especially about fluorescent light, it's the worst: it can add anything from green to red to yellow to blue tint to an object.
