A bit late to the discussion, but at least there weren't too many pages to catch up on before I got a chance to put in my 2 cents worth.
I like morph names to some degree. I know most of them, but still have to look up a few to make sure I have have all the genes involved (avalanche, whiteout and diamond mainly) and there are some I haven't even heard before, such as quartz.
I agree with the group that thinks the pattern morphs should have that part in the name. I think "blood"/"bloodred" should be limited to the dark red colored specimens, with maybe the exception of using it in combo with genes like hypo or lava where the snake is still red, but brightened/lightened by the addition of that other gene. Otherwise, the pattern morph is called diffuse, so a diffuse caramel, diffuse ghost, diffuse ice, diffuse Sunkissed (or Sunkissed diffuse) will be a more descriptive name for the morph. Yes, I know some snakes don't show much diffusion, but nobody has an issue with using low-, medium- or high- expression when it comes to pied-sided, so why not use it with diffuse to describe just how diffused it is.
Stripe and motley should both remain in the name. I don't agree with Mitch that the addition of stripe creates a more unicolor snake. It doesn't. It creates a snake with stripes, often very predominate stripes. The more unicolor stripes are already called "vanishing". When I first go into corn snakes, the more highly prized striped corns had full stripes that went the entire length of the snake and were quite distinct.
Sunkissed morphs are sort of special cases. Some trade names work quite well while I think some may not. I know Sunkissed amels have a trade name, but I can't think of it at the moment. Honey and orchid are basically second nature to me, but to call Sunkissed anerys anything else right now would feel alien. And then, what about Sunkissed ghosts? I have one that was actually called a Sunkissed silver queen when I got her. And mixing Sunkissed with certain other genes creates some very unique markings. Shatters and Sunkissed stripes come readily to mind. To mess with Sunkissed stripes, IMO, would be bordering on sacrilegious, their look is so completely their own. You can add whatever color morph name you want to them, but Sunkissed stripe needs to be there.
The originally dilute anery motleys were promoted as blue motleys. That works for me, and calling dilute anerys just blue is fine. But you should also have blue stripes and blue diffuse (although for this particular morph, I would break my own rule and want to call them blue bloods, just because

). Dilute anery Sunkissed would be blue Sunkissed (Sunkissed blue doesn't sound as good...which does happen with Sunkissed...put that term in front or behind or in some cases, either way works). However, I will fight calling dilute Sunkissed/Sunkissed dilute by any other trade name. True, Walter I believe bred the first ones, but I honestly don't think anything else would work, at least from what I'm seeing in mine. One trade name that I think will go over quite well when the morph is actually made would be for dilute anery lava...if it's not called a blue ice, this whole trade name thing is just worthless! And blueberry should be for a dilute anery strawberry.
As far as I'm concerned, some trade names just "fit". They may not describe the morphs actual appearance in some cases, but is that so important? Some names will take some getting used to but with use and time, will either be accepted or rejected by the majority. The whole "granite" thing was a fluke. At the time, terrazo was almost unknown while diffuse anerys were becoming very sought after. The popular/desired morph combo got the name.
I can look at several example of some gene combos and have a hard time telling the difference so their name is the only thing that differentiates them to me personally. A blizzard, a whiteout, a blizzard stripe and probably anything else with amel and charcoal all pretty much look like white snakes to me. Add lavender, caramel, dilute and/or anery and it would still look the same...a white snake. There may be some exceptions, say if the addition of caramel increases some yellow coloration, but is it consistent in all specimens or only a select few that may actually have something else going on to add the yellow and it has nothing to do with caramel.
Oh, and the name "trundlefart" was originally a JOKE and only very recently has been used by some as an actual trade name for a snake carrying one motley and one stripe gene. The whole striped motley, motley stripe, motley het stripe and het motley het stripe confusion that is still going on was what brought trundlefart back from the depths of threads long forgotten here on CS.com. I sure didn't expect it to be taken seriously! And I don't think Chuck Pritzel did either and I believe he was the first to use it in a morph naming discussion.
My opinions on some of the currently suggested trade names...
magma for diffuse lava is okay
wraith for anery Sunkissed - I don't like it. It's too dark and evil.
shadow for anery Sunkissed...maybe, but what will you call a hypo anery Sunkissed?
honeycomb for caramel Sunkissed diffuse...I don't really have an opinion. I'm still trying not to confuse honey with topaz and vice versa.
Oh poop! I've typed far too much for a single post! Gonna go eat dinner now!
