Not all these varieties are still bred by Zephyr - colours I expect to have include:
black, agouti, chocolate, chcolate agouti, american mink, american cinnamon,
chocolate american mink, chocolate american cinnamon, russian dove, russian dove agouti, and also double cinnamon pearl.
Some agouti and cinnamon will have essex markings, and some black and agouti will have silken coats.

Examples of kittens at homing age
Note that the colours will darken and become richer with age, and agouti based colours develop stronger orange tones in adulthood.

Rats which don't exhibit any colour genes are either black or agouti. My breeding plans centre around rats exhibiting the american mink gene
which have very dark ruby eyes, and some rats will be agouti based (mink agouti is known as cinnamon).
Consequently most Zephyr litters for the american line will include:

black (not always very black!)	agouti (all agouti based rats have paler bellies):
american mink	american cinnamon

My core line now includes some russian blue based rats - combined with american mink this produces dove.

I will also be breeding some essex - these rats have fully white bellies, a head marking which will range from
a small spot to a full blaze (and all possible splodges inbetween), and the normal colour will be faded to a more pastel shade as they age.
There may occasionally be some with odd eyes (caused by the white markings migrating into one eye) e.g. one dark ruby eye as normal, and the other a lighter ruby.

In my efforts to get double minks and double cinnamons, I am currently only getting them in pearl.
Fully expressed pearl only have colour on the very tips of their coat, meaning they look like a slightly grubby white,
but cinnamon pearl still show the brown ticking, so appear as a light orange.
Pearl can sometimes be only partly expressed (aka dark phase), meaning the rat appears mink with a pale undercoat, and will look patchy during moulting.

Quicksilver is the result of combining the american gene with pale british blue (I no longer have this line).
If the platinum modifier is also present, then the lighter eyed result is platinum. Pale british blue rats may also appear from time to time.

Chestnut is a new variety which doesn't yet have a standard - essentially an orange rat with black eyes and a darker nose.
There are many shades but I am aiming for a rich orange that sits between UK cinnamon and topaz. (I no longer have this line)
The self version is called ash.
This line will also produce darker versions (dark ash and brown chestnut) and some pink eyed rats.

ash	chestnut
dark ash	brown chestnut
pink eyed ash	pink eyed chestnut

Havana is chocolate based american mink or cinnamon carrying the buff/topaz gene (I no longer have this line).
These have a paler creamier tone to their coat and lighter eyes than the straight chocolate based americans do.
Any buff or topaz based rats will be expressing american chocolate which causes dilution meaning a lighter coat and paler eyes than standard.
Chocolate rats may also appear from time to time.

Silken (aka silvermane), is a coat type resulting in silver tips to the hairs for self colours,
and gold tips for agouti based varieties, sometimes a facial mask effect when the base coat is dark enough, and a silky texture.
The silvering on poor examples comes and goes, but the coat retains its silken feel.

Some litters may include dumbos (although I am not selecting for them), and most rats will have some degree of silvering which will come and go through their life.
