RAL 310 25 15
Dark Fern Root
RAL 310 25 15 Dark Fern Root occupies hue 310, lightness 25, and chroma 15, a deep saturated green-yellow that recalls the concentrated richness of fern rootstock and the dark interior of old Victorian ferneries. It is ideal for botanical garden signage elements, heritage greenhouse interior finishes, and artisan herbalist display details. The moderate chroma at this dark level gives it a verdant intensity that feels rooted in centuries of horticultural craft and botanical exploration.
