RAL 310 70 05

Whisper Fern Haze

RAL 310 70 05 Whisper Fern Haze occupies hue 310, lightness 70, and a minimal chroma of 05, a near-neutral light tone that barely hints at green-yellow beneath its grey surface, like the blush of distant fern fronds in morning mist. It is a natural choice for minimalist interior schemes, premium ceiling finishes, and gallery spaces requiring the subtlest atmospheric freshness. The very restrained saturation gives it a timeless, architectural quality that blends seamlessly with any material palette.
