Lilac golden shaded — “pink”
The rarest thing we produce. A lilac base under golden shading gives a coat with no grey in it at all — warm, powdery and genuinely pink in daylight, deepening to a soft mauve in the shade. Lilac alone is uncommon in British Shorthairs; lilac carrying golden is rarer still, and the pairing that reliably produces it took years to assemble.
c = lilac · y = golden · 12 = shaded. “Pink” is the breeders' word for the rosy cast, not a registry code.
