Representative Belgian d'Ucclephoto — a dedicated image of this exact morph isn't available yet.
A lavender-diluted version of Mille Fleur: soft straw-blue ground with pale blue and cream spangling, very delicate-looking.
Keeper tips for this variant
Porcelain carries the lavender gene, which can cause brittle/fretted feathering — select for feather quality and keep foot feathers dry to avoid breakage.
