Delta E (ΔE)

A measure of how different two colors look. Below 1 the difference is invisible to almost everyone; below 2.3 most people can't tell them apart; above 10 they are clearly different colors. We use CIEDE2000, the modern standard.Full glossary entry →

  • CSS: black #000000 · ΔE 16.2
  • RAL 8019: Grey brown #3F3A3A · ΔE 0.6 · approximate

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 Eclipse 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: a 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: As a brand anchor it reads established and tactile; pair with a single vivid accent for energy.
  • Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
