The change regularity of pigment compositions and contents of different chili pepper fruits with different colors during their development was investigated.Thechili pepper peels were initially determined using a colorimeter to identify their chromatism index(L*,a*and b*).The chlorophyll,carotenoid and anthocyanin contents of chili pepper peel were determined by spectrophotometer,and the relationship between chili pepper fruit color and pigmen change was analyzed during the develop-ment.Based on Origin 21 software,chili pepper fruit color was visualized.Component analysis,clus-ter analysis,and correlation analysis were conducted at different stages of growth and development.The results showed:(1)the CIE L*,a*,b*color space could reflect the fruit color changes during the of chili pepper fruits.Twenty-six chili peppers were divided into four color groups,where the fruit color changes were as follows:green varying to orange-yellow,purple changing to red or dark red,green changing to red or dark red,and yellowish green or milky white changing to red.(3)L*,a*,b*values of chili pepper pericarp correlated with chlorophyll,carotenoids,and anthocyanins.There were differences in changes of L*,a*,b*values in fruit color during the development of fruits from different chili pepper materials.Specifically,L*and b*were negatively correlated with fruit chloro-phyll and carotenoid content,while they were positively correlated with anthocyanin content.In con-trast,a*showed the opposite relationship.
