Albino
Most commonly two copies of the albino gene (cc), but can be caused by having multiple dilution genes, for example blue, mink, and pink eye dilute (ddmmpp), or pink/red eye dilute Siamese/Himalayan (for example, chchpp)

Black Eyed White
Rather than being a colour, BEW is the effect of white spotting. Common genotypes include HeHe (two copies of the extreme white spotting gene), although there are several combinations of h-locus genes which will give the same - and which gene it actually is makes little difference when breeding, as long as it's h-locus. The rat must also be a dark colour underneath the white spotting (black, agouti, mink, etc)

Burmese
Non-agouti plus one copy of the Burmese gene, plus either two copies of the Himalayan gene, or one copy of the Himalayan gene and one copy of the albino gene (Bubuchch or Bubu chc where Bu is the Burmese locus). The version based on chch is preferred for show. It is possible to breed a version based on albino (Bubucc) but this lacks points. This colour can be bred in various shades, selective breeding is necessary for a warm pale body colour and distinct points.

Blue Point Siamese
LORR Dudley
Two copies of the Himalayan gene, plus two copies of the dilute gene (chchdd). Blue can be a range of shades from very dark to very pale, almost lavender. The best shade for Siamese would be the darkest blue possible, which gives the most shading and the best body colour.

Roan/Striped Roan
Roan. Recessive roaning gene (ro/ro). Most likely unnamed modifier genes control the amount of markings - the difference between full roan and striped roan. This marking can be bred in any colour but dark colours are more common.
Striped Roan. Recessive roaning gene (ro/ro). Most likely unnamed modifier genes control the amount of markings - the difference between full roan and striped roan. This marking can be bred in any colour but dark colours are more common.
NFRS-"Roan-a strikingly marked bi-colour variety, with roan colouration, symmetry and contrast being important impressions. Clearly distinct from existing marked varieties. Roans are born solid coloured, but from the age of about 4-6 weeks they start to exhibit roaning. This is a steady increase in the amount of white hairs intermingled with the solid colour, starting with the face, sides and tail root on the juvenile, then working its way up to the nape of the neck with the moult. With each moult the rat becomes progressively lighter, the final effect not really complete until the rat is well into adulthood. The roan effect is most pronounced on the face, around the rump and the sides.
Pattern: The Roan shall have as symmetrical markings as possible. The underside should be completely white.
Head: A wide inverted V shaped blaze, including the whisker bed, coming as close to the eyes as possible without touching the eyes, and coning to a point between the ears. Jaw line and underside of the head must be white. Eye colour to conform to base colour standard.
Body: From the head, the colour runs back covering the ears and continues along the body extending down the sides. Belly to be white.
Tail: Unmarked tail preferred.
Faults: White spots in coloured fur/ coloured spots in white fur. Brindled demarcation line. Lack of white on face and head or a completely white face or head."
NFRS-"Striped Roan-a strikingly marked bi-colour variety with roan colouration, symmetry and contrast being important impressions. Clearly distinct from existing marked varieties.
Pattern: The striped Roan shall have as symmetrical markings as possible. The chest, belly, sides and all the legs to be completely white.
Head: A wide inverted V shaped blaze including the whisker bed, coming as close to the eyes as possible without touching the eyes, and coming to a point between the ears. Jaw line and underside of the head must be white. Eye colour to conform to the standard for the base colour.
Body: From the head, the colour runs back covering the ears and continues along the body with no suggestion of a hood, in an unbroken horizontal stripe, symmetrical and as straight as possible. The stripe to be approximately 5cm wide. Demarcation shall be as clear cut and even as possible.
Tail: Unmarked preferred.
Faults: White spots in coloured fur/coloured spots in white fur. Brindled demarcation line, demarcation line too low. Lack of white on face or a completely white face. Stripe too narrow or broken, any suggestions of a hood."
