Metallic paint shifts with angle — LAB is an average; treat polish picks as direction, not identity.

What do ΔE, LAB, and OPI mean?
- OPI
- A global nail polish brand — a salon staple since 1981. Lacca compares your car paint against OPI shades; any lacquer library with LAB values would work the same way.
- ΔE (Delta-E, CIEDE2000)
- A single number for how different two colors look. <1 imperceptible · 1–2 close · 2–4 noticeable · 4+ clearly different. Lacca ranks with CIEDE2000, which weights lightness, chroma, and hue the way human vision does — more accurate than the older CIE76 for subtle greys and neutrals. Catalog files declare which formula was used so the math stays reproducible.
- L*a*b* (CIELAB)
- A color space designed to match how humans see color. L* = lightness (0 black → 100 white), a* = green↔red, b* = blue↔yellow.
- D65 / 2° observer
- Reference lighting and viewing angle for color measurements — roughly daylight at noon, seen head-on. Colors can only be compared when measured under the same conditions.
- Finish
- Solid — uniform flat paint. Metallic — aluminum flakes that shift with light. Pearl — mica pigments with soft shimmer. Multi-Coat — several layers (Tesla's specialty) for depth and richness. Matte — non-reflective.
- Catalog / SKU
- SKU is the unique product code for a single polish. The catalog groups many SKUs with a shared version and measurement conditions.
