What is ΔE and how do I read these labels?

ΔE (Delta E) is the international standard for how different two colors look to the human eye — we use the CIE ΔE2000 formula. 0 means an identical color; the bigger the number, the bigger the difference. Because we measure every filament with a spectrophotometer, these labels reflect the real filament color, not the brand's product photo.

Virtually identical ΔE 0–1 The eye can't tell them apart
Very close ΔE 1–2 Only visible side by side, up close
Close ΔE 2–5 A slight difference when placed side by side
Noticeable difference ΔE 5–10 Same color family, but a clearly different shade
Different color ΔE 10+ A different color — not a substitute
