What color is Dulux Slumber Seed?

Dulux Slumber Seed 90YR 51/109 is a muted, mid-tone beige with a noticeable blush-peach cast that keeps it from reading flat or grey. Its soft, low-saturation appearance suits bedrooms, sitting rooms, and hallways where a gentle warmth is wanted without using a strong pink. In daylight, this color can appear like a pale clay-toned neutral, while warmer evening lighting may bring its rosy undertone forward. Pair it with creamy off-whites, warm oak, linen, natural stone, and aged brass for a layered, grounded look. Slumber Seed is especially effective on full walls or painted cabinetry, where its subtle warmth has enough surface area to register.
