How does this work?

Match a brick photo to official LEGO color names using Lab color science — not live marketplace APIs.

Single piece

  1. Upload or snap a photo with even lighting on a neutral background.
  2. Tap the dominant color area on the preview to sample a pixel.
  3. Review the closest official LEGO color and confidence band.

Compare two

  1. Switch to Compare mode and load photos of piece A and piece B.
  2. Sample each piece the same way — similar lighting helps.
  3. Read the ΔE similarity score and same-color verdict.
