Coat Genetics

Official Colors & Pigmentation

From historic solid hues to recently approved multi-colored coats: how genetic pigment distribution determines purity and adherence to the official FCI Breed Standard.

Color in the Poodle is not merely an aesthetic choice, but the result of a complex polygenic interaction strictly bound to precise rules governing the pigmentation of skin, mucous membranes, and nose. Any depigmentation or color defect (such as a pink nose in dark-coated specimens) is heavily penalized in conformation judging and considered a disqualifying fault.

From a cynotechnical and dermatological standpoint, there is no chromatic distinction based on the dog's size. Whether dealing with an imposing Standard, a balanced Medium, a Miniature, or a tiny Toy Poodle, the regulations regarding coat phenotypes and pigmentation apply identically. All Poodle coat colors derive from the modulation of just two base pigments: eumelanin (responsible for black and brown tones) and pheomelanin (responsible for shades ranging from rich red to pale fawn).

Solid Coats (One Color)

Black

Determined by the genetic dominance of the K allele and a high concentration of intact eumelanin, this coloration must be pure, deep, and glossy. Any white spot is considered a severe fault. Pigmentation of the skin (which often exhibits a slate-grey hue) and mucous membranes must be total and absolute.

Official Pigmentation Details
  • Coat:Pure, deep black without any rusty tinge.
  • Skin & Mucous Membranes:Strictly black, including palate and gums.
  • Nose, Lips, Eyelids:Intensely black.
  • Eyes:Black or dark brown, almond-shaped.
  • Nails:Black.
White

Despite the complete absence of pigment in the fur, the white Poodle is not genetically albino. It requires strong cutaneous eumelanin production to create a stark morphological contrast. Slate-grey (silver) skin is highly sought after and essential for dermatologically protecting the dog from solar photosensitization.

Official Pigmentation Details
  • Coat:Pure white, spotless, and free from cream or apricot shadings.
  • Skin:Slate-pigmented (silver) skin is strongly preferred.
  • Nose, Lips, Eyelids:Strictly black.
  • Eyes:Black or dark brown.
  • Nails:Full chromatic range allowed: from natural horn color to black.
Brown

Resulting from the recessive gene on the B Locus (bb genotype), eumelanin is altered to convert black into brown. It is the only solid coloration where black mucous membranes are morphologically replaced by brown pigment. The coat must maintain a warm, solid shade over time, avoiding degeneration into faded or beige tones.

Official Pigmentation Details
  • Coat:Deep, dark, uniform, and warm. Faded shades are strictly forbidden.
  • Nose, Lips, Eyelids:Dark brown, harmonizing with the coat.
  • Eyes:Black or dark brown. A deep amber tone is permitted; light eyes are never allowed.
  • Nails:Brown or black.
Grey

Genetically, the puppy is born black and undergoes a progressive lightening process (known as "clearing", driven by the G Locus) that stabilizes between 18 and 36 months of age. The adult grey must maintain perfect equilibrium: it should not degenerate into white nor retain blackish patches.

Official Pigmentation Details
  • Coat:Uniform and deep across the entire body. White spots constitute a severe fault.
  • Nose, Lips, Eyelids:Strictly black.
  • Eyes:Black or dark brown.
  • Nails:Black.
Fawn (Apricot and Red)

Regulated by the E Locus (ee genotype), this category expresses pheomelanin exclusively. Modifying polygenes, termed "Rufus", determine its intensity and saturation, spanning from soft apricot to rich mahogany red. The primary breeding goal is preventing fading over time.

Official Pigmentation Details
  • Coat:Solid, warm, and uniform across the entire body. Ears may sometimes be slightly darker.
  • Nose, Lips, Eyelids:Black or dark brown. In light fawn specimens, pigmentation must still remain as dark as possible.
  • Eyes:Black or dark brown.
  • Nails:Pigmented as dark and intensely as possible.

Multi-Colored Coats (Other Colors)

A monumental milestone in modern Poodle cynotechnics occurred with the official update to the Fédération Cynologique Internationale Breed Standard on August 1, 2024. This fundamental revision removed decades of show exclusions across European rings, fully incorporating and meticulously regulating the "Other Colors" category. Dogs with more than one coat color can now officially compete and be evaluated under the standard.

Parti-Color and Mantle (Tuxedo)

Genetically dominated by the S Locus (Spotting), Parti-Color dogs exhibit a clear white base with irregularly distributed pigmented patches. Approved combinations include: White & Black, White & Brown, White & Blue/Grey, and White & Fawn. The Mantle (Tuxedo) pattern is also recognized, where color dominates the back and head, leaving the chest, legs, and sometimes the tail tip white.

Phantom (Black and Tan / Brown and Tan)

Driven by the A Locus ('at' agouti allele), this pattern features a dark dominant base (Black or Brown) paired with well-delineated fawn tan points. To meet morphological criteria, tan markings must be positioned precisely: on the cheeks, above the eyes (eyebrows), inside the ear pinnae, on the sides of the muzzle, on the chest, around the perianal/genital region, and on the distal and inner parts of the limbs.

Tri-Color and Brindle

The Tri-Color pattern combines white markings with a black base and mandatory fawn tan points (present at least on the eyebrows and genital region). A major innovation is the official acceptance of Brindle patterns (governed by the K Locus, 'kbr' allele), where a fawn background is crossed by distinct dark eumelanin stripes, including Brindle with white.
