4-Locus Ultra-Rare
New Shade Lilac Platinum
e/e + d/d + b/b + co/co — the rarest four-gene combination in French Bulldogs. The genetic unicorn of the breed. Visually ethereal, genetically unmatched.
Model 4-Locus PairingsFour Genes Create NSL Platinum
NSL Platinum requires four separate recessive genes at four different loci. Each one plays a critical role in creating the ultimate exotic Frenchie.
E-Locus (e/e)
The cream gene masks all visible pigment. Without e/e, the dog would show its base color (Isabella). e/e makes the dog appear cream-white.
D-Locus (d/d)
Dilute lightens all pigment. Combined with chocolate and cocoa, it creates the ultra-pale Isabella base hidden under the cream mask.
B-Locus (b/b)
Chocolate changes black pigment to brown. This is the first layer of the hidden exotic base underneath the cream mask.
Co-Locus (co/co)
Cocoa further lightens the brown pigment. Combined with b/b and d/d, it creates the lightest possible Isabella base — the 'New Shade' effect.
Why NSL Platinum Is So Rare
Each additional locus halves the probability. Four loci create a statistical unicorn. Here's the math.
1 Locus
e/e or d/d25% from two carriers (E/e x E/e)
Single-gene recessive outcomes are common. Most breeders can predict these easily.
2 Loci
e/e + d/d6.25% from two double carriers
Two loci require both parents to contribute two recessive alleles. Already getting rare.
3 Loci
e/e + d/d + b/b1.56% from two triple carriers
Three loci drop below 2%. This is Platinum territory — already extremely uncommon.
4 Loci
e/e + d/d + b/b + co/co0.39% (1 in 256) from two quadruple carriers
Four loci is the statistical edge of possibility. This is why NSL Platinum commands the highest prices in the breed.

What is a New Shade Lilac Platinum French Bulldog?
A New Shade Lilac Platinum French Bulldog is produced by stacking four recessive genes: e/e (cream at the E-locus), d/d (dilute at the D-locus), b/b (chocolate at the B-locus), and co/co (cocoa at the co-locus). The e/e gene masks all visible pigment, producing a cream-white coat. Underneath, the dog carries d/d + b/b + co/co — the full Isabella genotype. This is the rarest possible four-locus combination in French Bulldogs and represents the absolute pinnacle of exotic color genetics.
How is NSL Platinum different from regular Platinum?
Regular Platinum is e/e + d/d + b/b (cream over lilac). NSL Platinum adds the co/co cocoa gene, making it e/e + d/d + b/b + co/co (cream over Isabella). The co-locus further lightens the hidden base pigment, so when the dog is bred to a non-cream partner, the colored puppies have an even lighter, more champagne-toned expression. NSL Platinum carries four recessive loci instead of three, making it statistically much rarer.
What makes NSL Platinum the rarest Frenchie color?
NSL Platinum requires four separate recessive genes at four different loci: E-locus (e/e), D-locus (d/d), B-locus (b/b), and co-locus (co/co). The probability of producing this combination from two carrier parents is approximately 1 in 256 (0.39%). Each additional locus halves the probability, and four loci create an extremely rare outcome. A dog that is homozygous recessive at four loci is the genetic unicorn of the Frenchie world.
How much does a New Shade Lilac Platinum cost?
New Shade Lilac Platinum French Bulldogs are among the most expensive dogs in the world, typically costing between $20,000 and $40,000. Prices can exceed $50,000 for exceptional examples with perfect structure, full health clearances, and the palest cream expression. Adding the fluffy gene (L/L) can push prices to $60,000 or more. The extreme price reflects both genetic rarity and the visual impact of a near-white dog carrying four hidden exotic loci.
Can DNA tests identify NSL Platinum?
Yes, but you need a comprehensive panel. NSL Platinum is identified by testing four loci: E-locus (e/e), D-locus (d/d), B-locus (b/b), and co-locus (co/co). Not all DNA panels include the co-locus test, so verify with your lab before testing. Embark, Animal Genetics, and DDC all offer four-locus panels that can identify NSL Platinum. The dog will test as e/e, d/d, b/b, co/co across all four loci.
How do you breed for NSL Platinum?
The most reliable way is to breed two NSL Platinum dogs together (e/e, d/d, b/b, co/co x e/e, d/d, b/b, co/co) — this produces 100% NSL Platinum puppies. Alternatively, you can pair dogs that carry all four genes but do not express them (e.g., E/e, D/d, B/b, Co/co carriers), but the probability is only 1 in 256 (0.39%). The DNA Calculator models these multi-locus probabilities so you can plan complex breedings with precision.
