I believe ANY interested party has the right to discuss morph names. I don't think it is egotistical to try to steer others to names you like or feel are most marketable. Whether your desired names will be become widely used is another matter.
The reality is that the people who sell the most of a particular morph, especially early in its existence, will usually try a name that they like, and that they think will help market the morph. That name often sticks and becomes accepted by most or all. Because the originator of a morph is usually in a position to sell the largest number in the early years, that person usually has an advantage in getting a particular name into general use and acceptance. BUT - the final decision of general acceptance lies with the snake buying public. If a name really catches the public fancy, or a name is not at all popular, breeders will usually go with the flow and start using whatever name most customers want to use. It just makes good business sense.
Some names just didn't catch on in the first incarnation. Eddie Leach first called his original bloods "corn gold". We didn't like it and neither did other early breeders. We came up with blood (I think blood corn, later blood red) and I think Ernie Wagner came up with tomato corn. Ours stuck.
Because we, Rich Z., and a few others, found and developed many of the first mutations and/or selectively bred morphs, we often got to try out some of the first morph names. Some stuck, some didn't. My recollection is that when we first starting breeding charcoal bloods, we didn't have a good name until a customer suggested pewter. We liked it and it stuck. Rich came up with the name pepper (I thought maybe it was salt and pepper?) right after that, but pewter had already started to stick a little, so the new name wasn't needed. As far as I remember, we hadn't produced anery bloods at that time, so I don't think pewter was ever used for them.
OTOH, we discovered the mutation for the striped, blotchless yellow / glades rats back in 1979. We tried a lot of different names to try to both describe it and market it. No mater what we tried, we just never found a really catchy, but descriptive name. I think that is one of the reasons they never got as popular as they should have been, based on their looks. We don't breed them anymore, but I don't know that anyone ever came up with a good name to this day. So a good, marketable name is really important, IMO.
The whole point of this side bar is that it is my take on how the naming process works, for those new to the hobby or who haven't thought about it much. Anyone who wants to can suggest names, and it may or may not take off. I kind of liked the idea of calling non-red bloodred combos "diffused" since I thought that it accurately described the pattern, without the confusing color connotations. But it has not really caught on. As a business person, I have to offer descriptions of what will help sell the snakes and not confuse customers anymore than necessary. So I have to use diffused either not at all, or as a 2nd description in the same way I use amel / red albino and anery / black albino. Whether or not I think they are good or proper names is not as important as the fact that my novice customers must be catered to and must be able to make an informed purchase with as little confusion as possible. After they see a name they like on a few sites and maybe a book or two, they begin to associate with the morph it describes. The more people who see a name in more places, the more likely that name will stick.
As for the name choices, although silver has a nice sound, many of us from the US, Canada, Europe, etc, may not be aware that keepers in South Africa call anerys silver. Although most of us won't be corresponding or trading with that country, I do get quite a lot of emails from keepers there. It was pretty confusing at first when they discussed silvers, until I figured out what they were talking about.
