The relation between visual color and photoelectric measurements of spaghetti color was studied. Two photoelectric reflectance colorimeters equipped with tristimulus color filters were evaluated by taking quadruplicate readings on 40 spaghetti samples which represented a wide spectrum of colors. Using the CIE system, reflectance data were converted to trichromatic coordinates and related to visual spaghetti color scores. Statistical analysis showed a high correlation between visual and reflectance measurements of colors.
