Detail Features
General
This page deals with colours regarding non-fur parts of the pets. Some of these are visible in pose, and others aren't. While we do not require all of them in the registration pictures, we do encourage to use realistic colours for these body parts of the petz.
If a pet is found to have a wildly unrealistic colours, the judge may DQ that pet. After all, the PKC was based on realism and UKC Conformation continues this. Realism includes the whole pet, not just its coat.
Eyeballs
Dogz and catz may have pure white (it's recommended, especially now with palettes, to use 245 for pure white) or off-white (201) eyeballz. It is now acceptable for either species to have eyeballs of either pure white or off-white. Both eyeballs must be the same colour even in P-reg petz.
Other shades of pure white are permitted (hex code #FFFFFF) but be warned that petz, by default, remaps some of the colours on its palette, so an index that shows up as pure white on the palette may not show up as pure white in game. Downloading and installing Prism's Modified Petza and making sure that 'Unlock palette' is checked in the PetzA settings fixes this remapping issue and means that colours will show up in game as they do on the palette.

Eyerims
Eyerims are the outlines around the eyes. All breeds and species are allowed to have black eyerims without fault at UKC.
Dogz
You can change a dog's eyerims to blue, liver, or flesh but only if that pigment type is allowed in the breed. For instance, if a breed allows black or liver pigment, you can use either on your dog's eyerims. But if the breed only allows black pigment, you can't give the dog pink eyerims unless specifically mentioned in the breed standard. A good guideline is to look at the nose and liplines - eyerims tend to be the same shade, or a similar one, to them.
If the eyerims are an allowed pigment type for the breed, but a mismatched colour (such as blue eyerims on a liver dog), the dog is faulted, just like it would be for wrong eye colour.
Catz
Catz can have eyerim colours other than black, just like dogz. However as catz do not have strict pigment requirements, the shade choices are less strict. The general rule is that the nose leather and eyerim colour (if not black) should coordinate, and highly mismatching eyerim pigment is considered a fault (such as light pink on a black cat). There are a few exceptions:
- Tabbies (including torbies, tabby/torbie points/mink/burmese, and leopard), if the eye rims are not black, are preferred to have eye rims matching the pigment of the stripe colour, and matching the nose etching (if present; nose etching is an optional marking)
- Silver and golden shaded and chinchilla catz must have either black eye rims or eye rims in a dark pigment matching the tipping colour. Light pigment is faulted.
- Torties (in all their forms) as well as all catz with white spotting may have multiple shades of eyerim pigment - both eyerims do not have to be the same colour.
Tongue Colour
Suitable colours for the tongue are red, pink, and shades of these colours. Some breeds (mainly the Chow Chow, Shar Pei, Thai Ridgeback Dog, and Eurasier) can have a blue-grey or slightly purple-toned (so called "black") tongue. Dogz of most breeds may have a few "black" (same shades as for the Chow, etc above) spots on their tongue.
By default, catz and dogz use the 70s index range for the tongue colour (and some dogz use the red at index 1). If using a palette, the colours displayed using this index colours may be different. It is recommended in this case to change the tongue to an appropriate red or pink colour.
Pawpads

Pawpad colour generally follows the tone of the coat - a good guideline (especially in catz) is to match it with the nose. Cream, golden, and red dogz often have black or dark grey. Animals with white feet often (but not always) have pink pawpads. They can also have ones that are a mix between pink and matching the coat. Liplines should also be untextured, matching the nose.
If you have, for instance, a black pet with pink pawpads, it will not be disqualified, but we do encourage to use the correct colours when possible. Using a palette may change the pawpad colour that the breedfile uses as default to a different, and maybe not appropriate, one - it is recommended in this case to change the pawpad colour to an appropriate.
Take care not to anchor the pawpad paintballs when anchoring the paintballs on the rest of the pet. Anchoring the pawpad paintballs will likely cause them to show up on the front of the fingers/toes - this is not accepted for A-reg.
Liplines/Nails
Only used in dogz files. As a rule of thumb, liplines and nails should match the nose pigment. Black in dogz with black pigment, brown in dogz with liver pigment, blue in dogz with blue pigment, and blue or flesh in dogz with isabella pigment. They do not need to be the exact same shade as the nose, but are normally within the same range.
When a dog has white feet, the nails can be pink/white/grey, but dark nails are still accepted without fault, as is a mix of light and dark nails.
Incorrect lipline/nail colour is faulted. The exception is if it's completely wrong for the breed all together (like having blue liplines on a breed that only comes in black pigments) - then it is a DQ.
Whiskers
Almost all catz have whiskers, with the exception of a very select few files. Curly/rex coated catz sometimes have uneven or extra small whiskers, and some other catz can have very large ones. All catz should sport the same type of whiskers as the file was accepted with. A double set of whiskers, or a complete lack of them, is not accepted, unless that's what the file was accepted with.
Any realistic colour is an accepted whisker colour. We encourage to use a whisker colour that is realistic for the cat's coat colour, but it's not required for A-registration that it matches the coat. If unsure on what colour to use, white or grey is a good bet as you can find cats of all colours in RL with white/grey whiskers.
Dogz that have whiskers are allowed to have realistic colour whiskers.
Noses & Noseshines
Noses must be untextured or use a dedicated nose texture (found in the texture library). It is not realistic for them to be fur textured.
Catz must not have nose shines. Dogz must have at least one noseshine, which must be white and untextured.
For dogz without addball noseshines, you are allowed to add your own in should you need to. As long as the final result looks fine in pose, you can use whatever code you wish. One code previously accepted by PKC (created by Emmer) is:
;addball nose
17, 0, 0, -5, 245, 0, 0, 0, 0, -1, 10, 0, 0, 0
41, 0, 0, -5, 245, 0, 0, 0, 0, -1, 10, 0, 0, 0
Place the code snippet at the end of the addballz section, then change the outlines of ballz 17 and 41 in the ballz section from -3 to -1. Some breeds may require a smaller noseshine - size 8 is recommended in this situations.
For PF Magic breeds with only a single nose ball (Chihuahua, Papillon, Pug), use:
;addball nose
55, 0, 0, -5, 245, 0, 0, 0, 0, -1, 12, 0, 0, 0
Ear insides ('linings')
Some files are hexed to have ear insides (or 'linings'). You cannot add them to a file that was not accepted with them, but you can choose to make them the same colour of the rest of the ear in files that do have them. They can be untextured flesh, untextured fur coloured, or textured fur coloured. In 2nd gens, they commonly revert to the same colour as the rest of the ear; this is not faulted. If there is fuzz on the ear insides/linings, it is considered fur (ear fluff) and must be textured and fur coloured.
For colour guidelines, untextured flesh colours should coordinate with the nose colour, although they do not have to be the exact same shade. If not matching the colour of the nose, ear insides ('linings') must harmonize with the coat colour. Ear fluff (textured, fuzzy ear insides/linings) should generally match a light tone in the coat (ex. black in black self, but base or light marking colour in a black tabby, and white or light in a black smoke).
Eyelids
All UKC A-reg petz must have eyelids. They should coordinate with the colour of the coat. Matching eyelids are preferred. The greater the contrast from the surrounding coat colour, the less preferred they are, to the point of becoming faulted - eg. orange eyelids on a black pet would be a fault.
An exception to this rule is when there is no single good eyelid match for the pet. This may occur when:- A texture is used, e.g a seal or lilac texture. It is preferable that you aim to match these as close as possible, however failing that, black eyelids are accepted and seen as equal to matching eyelids
- The pet has a different colour behind each eye eg. a tortie cat that has black on one side of the head and red on the other. Eyelids must both be the same colour in petz, so in these cases, eyelids matching any of the colours behind the eyes are acceptable and are seen as equal to fully matching eyelids. For example, the aforementioned black and red tortie cat may have either black or red eyelids.
SCP
You are allowed to change the SCP of a file. This changes the personality of the pet, which changes their expression when posing It is acceptable to change the SCP to any other SCP accepted for any files of that breed at any time. It is always forbidden to change the file to an SCP that is not already accepted for that breed. For example, at the time of writing, the Balinese has files accepted with Siamese, B&W Shorthair, and Russian Blue SCPs, so you can change the file you're showing to match any of these.
