The present study was conducted to determine the color characteristics of egg yolk in the eggs of layers ATAK-S [Barred Rock I (BAR1) and Rhode Island Red I (RIR1)] parents. Twenty five weeks old ATAK-S layer parents were divided into 7 treatment groups of similar mean weight
(including 60 female and 10 male) in Agricultural Biotechnology Department, Ahi Evran University. Parents ATAK-S housed were employed a 16:8 hours light: dark photoperiod. Feed and water were given ad libitum. Layers were fed standard layer diet having 17 g crude protein, 3.8
g calcium and 2800 Kcal ME in each kg. Experiment was carried out 48 weeks (between 25 and 72 weeks) and a total of 4032 egg yolks were analyzed. L* a* b* values were measured with photo colorimetric method of the CIELAB system and E (color difference) value, hue, saturation
(Chroma), Ho value were calculated. To conclude, overall mean of L*, a*, b*, E, hue, saturation (Chroma) and Ho value were 68.07+0.060, 25.15+0.097, 34.57+0.068, 80.53+0.057, 0.95+0.002, 42.86+0.068 and 53.94+0.129, respectively. This work was supported by the Republic of
