This pairing gives you 50% Italian / Manchurian gold and 50% Pharaoh (wild-type brown).
None of these chicks will lay blue eggs — but every single one carries the celadon gene and will pass it on. This is exactly how blue skips a generation and reappears.

Yellow: Dominant and homozygous-lethal. One copy gives the gold Italian / Manchurian look; chicks that inherit it from both parents die in the shell, so every living gold bird carries exactly one copy.
Celadon is an egg-shell trait, not a plumage variety. A celadon bird is modelled here as wild-type Pharaoh plumage carrying two copies of ce — if your celadon line is also colored, run the plumage cross separately.
The ce gene is recessive: a hen needs two copies to lay blue, and roosters carry it invisibly. Celadon × celadon breeds true for blue eggs. A celadon hen's daughters by a non-carrier male all carry one copy and lay normal eggs — which is how blue 'disappears' for a generation and returns.
Full Celadon (Blue Egg Layers) guide →Yellow heterozygote. No living Italian is homozygous, because double-Yellow embryos die in the shell.
Italian is built on the Yellow (Y) mutation, and here's the rule: Yellow is homozygous-lethal. Chicks that inherit Yellow from both parents die in the shell, so every living Italian is heterozygous. Italian × Italian hatches run about 25% smaller than expected (the lost double-Yellows) and throw ~1 in 3 Pharaoh-colored chicks. Italian × Pharaoh gives you roughly half of each with no losses — the smarter pairing.

Quail Keeper Max stores every bird's variety and celadon status, builds 4-generation pedigrees, and predicts the hatch from your actual pairings — so the invisible carriers in your covey stop being invisible.
