RAL values are widely published approximations of the physical standard. For Pantone-adjacent workflows, match by eye against a physical fan deck — Pantone's values are proprietary and device-dependent, so we don't print lookups.

Where Heron works

• Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
• Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
• Fashion: Works as a base layer or outerwear tone that lets brighter pieces do the talking.
• Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
• Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
• Fashion: One garment in this color carries an outfit; two starts to compete.
