Duck Egg Blue is a very light muted white with a neutral cast. Matching it is straightforward: Citadel Ulthuan Grey lands at 87 percent in the same finish, and 3 brands in all carry a close same-finish swap. It builds a smooth gradient with US Gull Grey underneath and Linen on the highlights, all in the Humbrol line. Treat it as an easy swap, just confirm the finish type matches before you commit.
Duck Egg Blue equivalents in other ranges

Closest Citadel equivalent: Citadel Ulthuan Grey, a near match with visible drift up close (delta E 2.5).
From AK Interactive: AK Interactive Duck Egg Blue Fs 35622, close, with a hint of drift side by side (delta E 2.9).
Scale75's closest color: Scale75 Sexy Zombie Skin, a near match with visible drift up close (delta E 3.1).
Nearest in the Two Thin Coats catalog: Two Thin Coats Ion Blue, a usable stand-in rather than a twin (delta E 5.4).
The drift here is spread thinly across hue, lightness and saturation rather than leaning one way, so the mismatch reads as a general haze at delta E 2.5 rather than an obvious shift.
