Concrete inputs and the matches the tool returns. Useful for spot-checking expected behavior before you trust the output for a real job.
| Input | Result | Notes |
|---|---|---|
| rgb(200, 16, 46) | Pantone 186 C, ΔE ≈ 0.1 (Coated) | Strong primary red — well inside coated gamut, near-perfect match. |
| rgb(255, 105, 0) | Pantone 165 C, ΔE ≈ 1.3 (Coated) | Saturated orange — ΔE under 2, indistinguishable to most viewers. |
| rgb(20, 40, 160) | Pantone 286 C, ΔE ≈ 4.0 (Coated) | Deep blue, classic corporate — Pantone is slightly less violet than the sRGB value, expected gamut shift. |
| rgb(0, 177, 64) | Pantone 354 C, ΔE ≈ 2.0 (Coated) | Bright green — at the boundary of perceptual identity; check against a physical chip for brand-critical sign-off. |
| rgb(255, 0, 255) | Pantone Rhodamine Red C, ΔE ≈ 6.5 (Coated) | Pure magenta — out of standard coated gamut. ΔE > 5 is a clear visible shift; consider Extended Gamut or a fluorescent Pantone. |
Common mistakes to avoid
Inputting Adobe RGB or P3 values as sRGB
Treating 0–255 RGB as linear
Ignoring the ΔE on a low-saturation gray
Forgetting display calibration before sourcing the RGB
Frequently Asked Questions
What “RGB” actually means in this converter
We treat the input as 8-bit sRGB — three integer channels from 0 to 255, encoded per the IEC 61966-2-1 standard with a D65 white point and the sRGB gamma transfer. This is the same color space assumed by every web browser, modern operating system, and uncalibrated office monitor.
If your source values are Display P3 (modern Apple devices), Adobe RGB (1998), or DCI-P3 (digital cinema), the numerical RGB integers are not directly comparable to sRGB. Convert through your color management software before relying on the Pantone match, or expect a small ΔE penalty caused by the silent mis-tag.
How the match is computed
Your sRGB triplet is first linearized (inverse gamma applied), then transformed to CIE XYZ using the standard sRGB primaries-to-XYZ matrix, then to CIE Lab via the Bradford-adapted D65 reference white. CIEDE2000 distance is computed in Lab against every reference Pantone (Coated or Uncoated, your choice). The top six matches are sorted ascending by ΔE.
The Pantone reference values themselves are pre-converted to Lab once at build time, so the matching is fast and deterministic — no rounding drift between page loads.
ΔE thresholds for production use
- ΔE < 1: imperceptible to a non-trained observer; production-safe under any normal viewing condition.
- ΔE 1–2: barely perceptible side-by-side; acceptable for almost all brand work.
- ΔE 2–5: visible to a trained eye; document the shift in brand notes and confirm with stakeholders.
- ΔE > 5: clear visible shift — the source RGB is out of gamut or on the edge. Use an Extended Gamut process or rethink the brand color for print.
When RGB → Pantone is the wrong direction
If you already have a target Lab measurement (from a spectrophotometer or a press sheet), do not detour through RGB. Use the LAB → Pantone converter instead — Lab is the device-independent space the matcher actually works in, and skipping the sRGB → Lab step preserves your original signal.
