Cat Flap in a Rockdoor Duck Egg Blue Door
A pale, chalky blue popular on coastal properties and modern farmhouse-style homes — one of Rockdoor's best-selling non-neutral colours.
Duck Egg Blue Rockdoors need a delicate touch — the pale finish shows any cut-line dust, so we mask and vacuum continuously through the install. White-framed flaps blend far better than grey or brown on this colour.

The pale palette calls for a white flap frame — grey or brown would look heavy against the soft Duck Egg tone.
