Maybe you have seen poor examples of Dark Cornish and/or Dark Brahmas. The penciling should be the same in both. What genes are at work in the Dark Cornish pattern that are not present in Dark Brahmas?
The true Coronation Sussex was blue, not lavender. Even the link you psted said that.
Columbian became a recognized term for a particular trait. Coronation and Jubilee were use for only specific instances.
Type and tightness of feather are very different in Jubilee Orpingtons and Speckled Sussex. Look for good examples of each, not just random birds.
I am aware of lavender/self blue and blue. The original Coronation Sussex, and the UK recreation were blue, and the Australian recreation, which is recreated on the US, is lavender.
The event is not the issue. It is whether something is an accepted term or not. If one randomly assigns a name to something, what does it help? Plus, the picture you posted is neither Columbian nor lavender. Blue and lavender are not mislabeled by people who know and understand what they are talking about.
Wikipedia isn't written by poultry fanciers as I've stated I'm American, and where I am, Coronation Sussex are lavender. Lavender, blue and gray are all frequently mixed up, especially when dealing with historical data and articles written by people who don't actually know anything about the genetic basis for any of the phenotypes, so I count a lot of blue/gray/lavender stuff out the window when I know it wasn't written by someone who knew the difference between those terms.
Different opinions don't make me inferior in knowledge to you. I put the thread here because it's about genetics and breeding, not "stories of my chickens". It actually is about making and designing a breed, even if you can't be arsed to read the whole thing. It's an exercise, a work in progress, a way to inculcate knowledge and learn about what goes into to making and perfecting a breed. This conversation fits here, whether you're posting here or not. All breeds started out just like I'm starting out--with a few birds and some ideas as to how to make them better.
None of the birds termed Coronation Sussex are the same color as the original which, as I've stated had red in them and were "patriotic as Union Jacks". Nobody has the "real thing" so American Coronation Sussex are probably just as fake as English Coronation Sussex. The coronation never happened. It's the only bird named for a coronation, so it does work as a color for the exact same reason as the Columbian Exposition can double as a color (because there weren't any other birds named for it), and it's the most succinct way to describe that color.
Speckled Sussex and Jubilee Orpingtons are the same color here. Feather type does not have anything to do with color (though some colors impact feather quality, which is different). They're the same color the same way mille fleur D'Uccles are the same color as mille fleur Leghorns and Cochins. Basically mille fleur with darkening modifiers like mahogany, because they're more of the deep red instead of the gold color of mille fleur. Or at least, Jubilee Orpingtons and Speckled Sussex are the same color *over here*.
It not my fault if birds look different on different continents, or that you don't know and won't research what birds look like here, or even look up what I'm talking about regarding Brahmas and Cornish (which really do have other modifiers that Brahmas don't have to have to be perfectly worthy Brahmas). Lacing involves a lot more than you apparently realize, which is why the lacing on multiple laced patridge looks different from Sebrights, looks different from Wyandottes, looks different from silver spangled Hamburgs, looks different from Dark Cornish *over here*. This difference is probably why are there different "male" or "female" lines for Dark Brahmas as these modifiers would make the lacing much cleaner and more exhibition worthy in females but would negatively impact male coloration (as Dark Brahmas are supposed to be comparatively close to wild type in color, but with silver and the pattern gene).
Also, maybe gold and silver look the same where you are, but here they're different colors--even without the modifiers that I was talking about (ergo, "dark"=/= "dark" always). Dark Cornish also aren't merely gold here because they're darker than "gold" and more like Buckeyes and heritage RIR, which have modifiers that deepen the pheomelanin color.
If I put on a tiara and called myself queen of my own backyard, my Coronation EE would have just as much factual basis in history as Edward VIII's, and I wouldn't get my panties in a knot if someone decided to use that term as a color in an ultra-informal setting since *GUESS WHAT?* nobody's going to be giving out brand new breeds/colors of chickens to any royal party at their coronation! It's not the 1800's anymore! Queen Victoria is dead! The whole shebang was her fault, so without her keeping the hen craze around, there's no longer fashionable influence enough in royal English-speaking monarchies enough to warrant the behavior that brought about the Coronation or Jubilee birds! Those are the only birds named with those monikers, and they will continue to be the only the birds with them until poultry fancy takes off to the absurd level it was at the time of Victoria's reign (and fueled, of course, by the bringing back of exotic breeds from far off realms). It's not going to happen again. New global world we live in isn't full of such isolated places and imperialism, so the thrill of finding exotic chickens has been drastically lessened. They're not worthy gifts anymore to superpower royalty, so there won't be any more Coronation Chickens.
Even if some bird was presented to another royal, it wouldn't be English-speaking, and therefore, "Coronation" wouldn't be the term (it would be a foreign term belonging to that country, in other words).
I've already repeatedly stated that I was using the term as shorthand for lavender Columbian because that's what Coronation Sussex look like here. He looks like a poofy-cheeked version of his Coronation Sussex ancestor, so its an apt shorthand, especially since everyone on this side of the pond would know what I was talking about (even though hardly anybody knows why the birds have the Coronation moniker). I'm sorry they don't look like that where you are and that you got confused as to why anyone would ever use the shorter term in place of the longer term in a thread that's mostly notes and updates about a pretty informal project to begin with.
This thread is a journal of sorts and where I'm backing up pictures and observations on the project in digital format so I can come back here and see how the project has progressed Lots of other similar projects exist on this site and in this subforum, and there shouldn't be any problems with that *because that's what it's here for*
I was pleasantly surprised that I'd found another person who was intrigued about the history of the breeds and colors.
Over here at least, Columbian refers to a restriction of the normal black pigment through the body (which this bird exhibits--unless of course you're looking at the wrong bird in those pictures) and adding the term lavender or blue means that the bird has the black coloration in the head and tail replaced with blue or lavender (which are just dilution factors of black). Adding the term buff just means the body is gold based instead of silver but that black is still restricted to the hackles and rear. He no doubt has other modifiers at work, but he definitely has lavender instead of blue or black, and he definitely has black restricted from his body. It's not uncommon--especially in heterozygous birds--for there to be some additional color present in saddles or farther down the neck/back between the shoulders. Because there is no eumelanin in his chest, I must determine that he at least carries one copy of Columbian. I'm never going to claim that he's some prize winning paragon of any standard color, but that does make sense when he's acknowledged to be a mix. Lavender Columbian is the closest approximation of his color. It's also not uncommon for lavender birds here to have cream lacing, especially in the hackles. It's not a good thing, but it happens often enough that people still recognize the birds as fundamentally lavender and may still use said bird in breeding programs (even if you wouldn't).
