Abstract excerpt

Eggshell color exhibits considerable variation, with the diversity particularly rich in shells where protoporphyrin serves as the primary pigment. The measurement of eggshell color typically employs the Commission International del'Eclairage (CIE) L*a*b* color space system, which precisely describes color based on three dimensions: lightness (L*), red-green (a*), and yellow-blue (b*). However, in comparative...
