Part Guess — Identify a LEGO Part From a Photo
Photograph one LEGO piece and Part Guess tells you its BrickLink part number, guesses its colour, and shows what that part sells for in that colour.
Why colour matters
The same mould can be worth a few cents in a common colour and several dollars in a rare one. Part Guess identifies the mould, samples the colour from your photo, and matches it to the colours BrickLink actually lists that part in. If the guess is wrong, pick the right colour and the price updates.
How to get clean results
Lay the parts out on a plain contrasting background so they don't touch or overlap, in soft even light; Part Guess finds and prices each one. For parts that look alike from the top, use batch mode and add a shot of the underside too.
