Cavapoo Color Genetics Explained
Cavapoo colors are a beautiful product of Cavalier and Poodle genetics colliding — and they're far more complex than most breeders let on. Here's how color actually works.

Why Cavapoo Color Is So Unpredictable
Cavapoos inherit color genes from two very different breed lines: the Cavalier King Charles Spaniel (with its ruby, Blenheim, tricolor, and black & tan expressions) and the Toy or Miniature Poodle (with its extraordinary range of solids, phantoms, parti, and abstract patterns). When these two gene pools combine in an F1 Cavapoo, the results can be genuinely surprising — and that's part of what makes each litter so unique.
The Cavalier Parent's Color Contribution
Cavaliers come in four recognized colors: Blenheim (chestnut and white), ruby (solid rich red), tricolor (black, white, and tan), and black and tan. The Blenheim pattern carries the parti gene (white spotting), while ruby dogs are solid red. Tricolor and black-and-tan dogs carry black pigment genes that can produce darker-based Cavapoos when crossed with Poodles.
- Blenheim Cavalier × red Poodle → often produces apricot/cream or parti Cavapoos
- Ruby Cavalier × red Poodle → rich red or dark apricot Cavapoos most likely
- Tricolor/black & tan Cavalier × red Poodle → can produce phantom, tuxedo, or sable Cavapoos
The Poodle Parent's Color Contribution
Poodles carry the most diverse color genetics of any breed — including genes for red/apricot (controlled by the 'e' locus), phantom pattern (tan points on a dark base), parti (white spotting), abstract (partial white), and sable (a banded hair pattern that produces striking shading). A red or apricot Poodle parent significantly increases the chance of warm-toned Cavapoo puppies.
The Most Common Cavapoo Colors
- Red — deep, warm red inherited from the Poodle's 'e' locus. Often fades to apricot as the puppy matures.
- Apricot — warm peach to orange tone. The most common Cavapoo color.
- Cream — very light gold to near-white. Produced when both dilution factors are present.
- Chestnut/Blenheim — inherited Cavalier pattern with red/brown patches on white.
- Black — solid black, most often from Cavalier tricolor or black genetics.
- Tricolor — black, white, and tan. Requires specific recessive genes from both parents.
- Phantom — dark body (black or brown) with tan markings. Rare and stunning.
- Parti — 50%+ white coat with color patches. Requires the parti gene from the Cavalier line.
Will My Puppy's Color Change?
Almost certainly, yes — especially for red and apricot Cavapoos. The 'e' locus that produces red pigment in Poodles is associated with progressive fading, which is caused by the progressive graying gene. Many puppies that are a rich, deep red at 8 weeks become apricot or gold by adulthood. This is normal and expected. A DNA color test on the parents can help predict fading likelihood, but cannot guarantee adult coat color.
How We Predict Color at Star Struck Puppies
We DNA test all breeding dogs, which gives us access to their full genetic color profile — including loci for base color, dilution, the extension gene (which controls red expression), the agouti gene (sable and tan point patterns), and the parti gene. This allows us to make educated predictions, though individual expression always varies.
