     In this paper,colorimetric methods were used to study the fifty-one samples collected from the fourth member of the Quantou Formation（K2q4） and the first member of the Qingshankou Formation（K2qn1） of ＂SKⅠWell＂ in the Songliao Basin,and get the following conclusions：（1） By using the CIE1976 L＊ a＊ b＊ color system,we found that the colorimetric index L＊ and a＊,b＊ and a＊ of the samples assume observably negative correlation（Negative correlation coefficient respectively achieve-0.564 and-0.663）,L＊ and b＊ were showed observably positive correlation.（2） By analyzing the correlation between the samples＇ colorimetric index L＊a＊b ＊and TOC%,we found that the b＊and TOC% were present more significant negative correlation.The correlation between TOC% and L＊and a＊ are not obvious.As part of the carbon cycle,organic carbon has important significance on paleoclimate research of the Songliao Basin,restricted by the total organic carbon content（TOC%）,the b＊could be a alternative index of the paleoclimate change.
