TrazaScale is a physical card with calibrated chromatic patches, a reference checkerboard, and corner fiducials. Print free at 100%. Include it in every clinical shade photo. TrazaTono and TrazaVideo detect it automatically and normalize color — it closes the gap between how you see the shade and how the lab sees it.
Without a physical reference in frame, the phone camera, the chair lamp, and ambient light shift the perceived color of the tooth. The lab receives photos that describe a shade that is not the real one. The remake is the outcome — not anyone's bad intent.
LED, fluorescent, and halogen lamps paint the shade differently. Your camera's white balance compensates — but not always well.
Your phone decides what is "white" in each shot. If the scene has no neutral white, it decides wrong. Two photos of the same tooth come out different.
Chromatic saturation gets simplified during compression. A3 and A3.5 can look identical after compression. The lab interprets "A3" as its A3.5.
The lab sees your photo. Without a known chromatic anchor in frame, its best bet is its experience with your practice. Sometimes it gets it right. Sometimes it does not.
TrazaScale puts a known and reproducible chromatic anchor in the same frame as the tooth. Eight grayscale and primary color patches, a VITA-aligned grid, a checkerboard for auto-detection, and corner fiducials for perspective compensation. The software corrects color against known references — the human eye can read the scale too.
The printed card works on its own — as a visual reference for any camera. Connected to the TrazaLab engines, it becomes an automatic calibration system.
cardPresence validator blocks the upload if the card leaves the frame during any scene.The numbers come from the TrazaLab research report on the global cost of dental remakes.
