I’ve been reading about using digital spectrophotometers to capture exact color data when matching paint on vintage vehicles. The idea is that the device measures wavelength reflectance and translates it into a formula for mixing. In theory it should reduce trial‑and‑error, but I wonder how reliable it is across different substrates and lighting conditions. Does anyone have experience with the accuracy of this method, or prefer traditional visual matching?
How does digital spectrophotometry improve paint matching for classic car restorations?

Thanks for bringing this up! I’ve used a handheld spectrophotometer on a few pre‑war Buicks and found it pretty consistent on metal, but it can struggle a bit on old wood‑grain panels or when ambient light shifts the sensor’s baseline. Do you calibrate the device with a reference tile before each job, or rely on the built‑in lighting?
