All Kiseilians have black eyes, they never had genetic alteration about their colours.
Kiseilians' sight it's also not really important as they rely more on other senses.
Kiseilians' mouth can have slightly different natural colours.
Their mouth colour can be darker or lighter than the basecoat, inherited from their parents or can have every natural colour showed here even if parents don't have it.
Unless the basecoat is Charcoal/Onyx you should always color your mouth and not leave it the basic grey already present in the template.
The mouth can't be saturated. Only with Malachite basecoat the Kise can have a more saturated greenish mouth.
It's possible to have patterns or different darker colours (up to 2) on the tongue and gums.
Tongue can have a different colour from gums or be the same.
Nostrils and the flesh around the eye can be coloured following the marking rules or the gums colour as you please.
It's possible to vary a bit their claws and teeth's colour.
Claws can have shades of Kise's body, be black, white pinkish or the same colour of teeth!
Instead, since teeth would show their health status and nutrition, they can vary from white to yellowish or greyish but can't have any other saturated colour or be black.
Fur's color acts like a marking over the belly color.
For example, if the belly is jasper you can use shades of red, hauyne, amber and heliodor for the fur.
However, if you have yellow belly when your basecoat is hauyne, you can use only heliodor allowed colors (hauyne, jasper, amber or malachite) because the fur interacts with it.
If markings respect the rule above, fur can have their colours.
This means that a yellow belly can't have purple fur, as well red can't have green fur.
It can have some gradient of the same colour and also minimal white and black can cover it! As well, markings can extend on fur as long as they follow the colours rule.
Remember that colours can't be too saturated; pictures above are only examples.
Males' wattles can have a different colour, but only one colour of their body (base colour or markings). They can't have weird design since their small size
