:V lil note that golden isn't tracked to alleles the same way you would expect because it hasn't been identified as a single gene- wb is used by some golden breeders usually to express the "degree" of gold and to track the presence of wideband!

Common notation is
Wb or -/wb/wb+/wb++ (non-wideband, slight wideband/shaded, medium wideband/shell, widest wideband)
The last of which loses all tipped marking except on the tail, and paler areas like underbelly are almost white- sometimes called extreme shell or extreme chinchilla.

It's almost certainly polygenic, which would mean more than one gene affects the resulting color and that's why it's so hard to pin down. There's also a theorized, very hypothetical gene they're calling "tipping" that changes how agouti is expressed, it's possibly why genetically Classic Tabby golden chinchillas have partially or totally broken up patterns that look ticked despite not being genetically ticked tabbies.

Very interesting stuff! It does however mean that the Golden Shell example here would probably be caused by a modfier rather than the shell effect itself causing the classic tabby to be dispersed. The theorized tipping behaves like ticked tabby, is semi-dominant even to ticked, but two homozygous ticked tabbies don't have tipped kittens.

It's actually been a theory for a looong time, the symbol being tentatively used for it is UU (homozygous tipping) and comes from the older theory "Unpatterned", basically it's supposed to- in theory- change agouti when homozygous to produce a ticked tabby but that has "bleached" roots.

Thought you might find that interesting! n.n I was just reading about it the other day~

Even from looking at supposed Bimetallic cats i dont doubt its polygenic! I appreciate the correction with the genes, as I have a lot of difficulty finding consistent information on them. Visually I struggled finding any chinchilla/shell that wasn't very long furred so its often harder to tell for me what exactly i should be visually representing on shorter fur.

I'll certainly be re-doing the text on this page and making note of that theorized modifier! It would certainly explain why many shells even look that way and looks similar to shaded ticking.

Take a look at British Shorthairs! They're a popular breed for shell and shaded!

edit; NWbritishcat cattery has beautiful kitties that are prime examples of golden and silver shaded! They've even got a silver shaded point queen who's absolutely serene! Check their website and their insta for a good look- their insta will have pictures of past cats/kittens so it's more variety of examples.

edit2; Alinagoldhouse has great shells/chinchillas (called, cutely, "shinshillas" on their website) as well for examples. Mostly goldens but with one tarnished silver lynx point Kassandra who is incredibly gorgeous.
Also check out "Arielle" in their "Kittens" tab on their website- she's a golden shaded without the posited Tipping gene (UU) who has fully visible Classic tabby! (even shows her parents, both with obviously ticked or tipped fur)

I did look to them for silver shells/chinchillas so i appreciate the specific catteries for reference! Goldens are such a pain to find anything on.

[Adamented]

They really are ;w;

Something you might want to consider making an example of as well, is smoke torties. Smoke torties tend to make the red very pale, even changing the stripes. It happens in tortie points too!

[~HєуRєι~]

The tort smoke and shaded are at the bottom! and the tort points are over on the second tortie page. All the reds on this page are mimicking the color that appears on the silver cats instead of the base color.

[Adamented]

Right, but what I'm saying is that smoke torties don't actually have their red patches identical to red silver tabbies- they're, for some reason, for the most part paler.

[~HєуRєι~]

From what I can tell that may not be the case? The brindling and brindling placement as well as the type of tabby underneath and fur length may make some cats look paler but from what I can tell, smoke tortoiseshells with larger patches visible of the red tabby seem to be the same as red smoke. If you can provide reference with bigger patches I'm more than happy to change the color.
The references I've specifically used for the red tabby color and tortoiseshell cats have been maine coons which have presented with classic tabby on red.

Of course I'm sure the intensity of smoke may also effect it, this is just meant to be a basic visual for the most part and I may go back and see if the red smoke itself is accurate enough once I'm done researching for dogs.
