RAL 270 25 20
Dark Treacle
RAL 270 25 20 Dark Treacle occupies hue 270, lightness 25, and chroma 20, a deep saturated golden yellow that recalls the concentrated warmth of dark treacle and the rich interior of aged mahogany humidors. It is ideal for heritage library shelving finishes, artisan chocolate packaging elements, and traditional joinery details. The strong chroma at this dark level gives it a syrupy intensity that feels rooted in centuries of confectionery craft and woodworking tradition.
