question
I am very unsure of the colour of my cat. He is a blue . . . Yes, but there is something else. His legs show no clear white, his face is covered by this caramel, besides the flanks too. His saddle is almost solid. But under the tail he is silver.
In his generations was always that colour again! All judges have repeatedly said . . . It is *blue-silver-shaded*, however, to dark, solid!!!

In order to answer the question we have posted the photographs in an order to understand and the pedigree is posted at the bottom

	Flame, the father of Fritz from pedigree he is red silver shaded A-B-D-I-ss--ww Sire Miamber Silver Khye, Black silver shaded Burmilla, A-B-D-I-oss--ww Dame  Bnfire Silver Crocus, red silver shaded Burmi;la A-B-D-I-OOss--ww genetically we see him as (using our nomenclature) A-,B-, Ccb?, Dd?, Ii, ll, Ox, Ta-, Wb-, swbswb that is Agouti  as u say -  probable homozygous Black,  minor possibility of b from Cassanova Full colour  - good possiblity of cb from Fleetwood mac who had to be cbcb Dense colour  heterozygous,  recessive from offspring - - d from dame and her lines Silver ,  heterozygous,  recessive from offspring and coming from Fleetwood Mac on both sides of pedigree additionally Silver Crocus (his Dam) had to be Ii Short hair  likely homozygous Red from discriptor Abby tabby  probable homozygous Wide band  probable homozygous Superwide band,  (speculated ) homozygous recessive
	Salome Dee Seal tortie silver shaded Salome, the mother of  Fritz. We are unclear as to what Seal is. we assume genetic black and pointing as in B-,cbcb genetically we see her as (using our nomenclature) A-,Bb, cbcb, Dd, Ii, ll, Oo, Ta-, Wb-, swbswb that is Agouti from the brick nose probable homozygous Black, heterozygous  - -recessive from dam Burmese sepia from discriptor as seal homozygous recessive Dense colour  heterozygous,  recessive from sire Silver ,  heterozygous,  recessive from offspring and coming from Fleetwood Mac on both sides of pedigree Short hair  likely homozygous Red tortie  from discriptor Abby tabby  probable homozygous Wide band  probable homozygous Superwide band,  (speculated ) homozygous recessive  and giving this tipped cat
	The grandmother from Fritz . . . Landon's Smaragde Perhaps, the grandmother of Fritz (Landon's Smaragde) are golden. Chocolate Silver shaded (A-bbD-I-ss--ww) from pedigree We agree the tarnishing around the nose and the off the side of the eye is curious. However there is nothing within the pedigrees that would clearly indicate golden in the line.  note our Thamakan source boy Findus has produced a golden so the golden can be carried a long way.
	A sister (from) of the father

Mother seal-tortie-silver shaded. Father red-silver-shaded. He has golden in the pedigree!!! The paw colour from Fritz is blue. And now . . . The colour along the top of the ridge is blue!!! And the tail oversize too. Perhaps, the approach is a mouse grey. But only at these points and over the top of the head we found a solid colour. Under the tail I have had a look with a whit paper . . . It is not whit. Over the whole cat is a cream glimmer. You can seen this of the photo with my another cat Käthe (The photo with the two on the scratching). Yes, I mean he is golden. But rest assured I can only upon with a mating with a golden. Perhaps it is only strong Rufismus (Oh sorry, I don't know . . . This is the right word in English!!!). I hope you know what I mean.

Answer
1) it is not totally clear to me as to the nomenclature that is being used on the pedigree provided with regard to the genetics.
however
a blue tortie is described as  - - aaB-cbcbddiiss--ww
and a red silver shaded is described as A-B-D-I-OOss--ww
it would therefore be our understanding that
A is Agouti, aa is self or non agouti
B is Black, bb is genetic Brown
C is not used, for full expression? colour but cbcb is Burmese restriction of Sepia
D is normal colour distribution and dd is dilute (smetimes called maltese gene)  as is a blue or cream cat
I is Inhibitor /silver and ii is golden
O is genetic Red Oo is tortie in females and  o is a non red male   Note  we do not understand why it is not noted in the pedigree info of Flame.

ss  --  and ww  - - I do not understand.
It is however  very interesting that these breeders are attempting to further define colour by genetics. That is great.

2) Ann and I agree that the kitten Fritz is blue/golden, and we are  quite sure of that .  - - - Is that possible??
He is From
Sire  A-,B-, Ccb?, Dd?, Ii, ll, Ox, Ta-, Wb-, swbswb
Dame  A-,Bb, cbcb, Dd, Ii, ll, Oo, Ta-, Wb-, swbswb
and is therefore
A-,Bb?,Ccb?,dd, ii, ll, ox, TaTa (probable), WbWb (probable), and swbswb.

A-  that  is Agouti   - -no question  he may well be AA  that is homozygous agouti vice A/a

B- that is genetic Black - - his mother from the pedigree would be Bb, his sire has genetic brown 3 generations back and you confirm the paw pads as blue  it is unlikely he is  genetic Brown - -  but there is a possibility  making him lilac???

C- this is the nomencalture I use for full colour   your pedigree says the mother is seal this would suggest to me that she is sepia  --genetic cbcb but I am unsure of how this term is defined ??? by you.    it would appear unlikely he is sepia (cbcb) from the photo   it is usually seen as a darkening around the ears and forhead but given that this is difficult to tell in a tipped or shaded cat,  - - it is possible, - additionally the dilutes also render this determination more difficult    - -in Canada we call a non sepia/ dilute /black indigo  and a sepia/ dilute/ black - -   Blue

dd   dilute - this has to mean that both parents carry d.   Salone does from her sire. Flame would have it from Fleetwood Mac and Silver Crocus so both cats are Dd and can be said to carry dilute.

ii   golden again both cats must carry i . Bellabony Fleetwood Mac is on both sides of the pedigree and he has i from Mary who is ii. Silver Crocus would also carry golden

ll  shorthair

ox not red

Ta  Abby tabby most likely homozygous

Wb  wideband most likely homozygous
and

swbswb super wide band homozygous recessive -  as a point of interest   (this genetics we speculate upon and) as this is recessive it is most desirable to keep in the breeding lines.

We do have one question  - - in Germany is a Burmilla allowed to be Golden and still be called a Burmilla?? - -not a problem for us in CCA.

With regard to golden and your boy we have the identical colouration in Lavina see super wide band  - proof the daughter of Claudius.
see also Bella Donna the daughter of Lavina.
Yes the judges argue with us and look at the silver in the underfur.  It is difficult to get them to see but the best way is to do as you and done by showing the silver and golden side by side or have a photo side by side. The use of paper is also a very good idea.

Remember genetics containing  Dilution, Sepia, Brown and Inhibitor all work to reduce intensity in the (C) colour genetics by 1) changing the colour dot distribution 2)  making it  temperature sensitive, 3) changing the colour dot shape, 4) destroying ?? the colour itself. Wide banding changes the frequency of the banding process and so also effects a colour change.
 Golden in a Dilute, Sepia and Brown (lilac)  is certainly difficult to differentiate from silver.

Stick to your guns. You are correct.

regards
and good luck
