The study of the chroma on the Huangshan (HS) Profile in the eastern part of the Northeast China Plain, a typical Quaternary Profile in Northeast China,has not yet been reported. Through study of the high resolution chroma parameters of the Harbin Formation loess- paleosol in the Tianhengshan core, correlation analysis was carried out with ignition loss, and was compared with the curve of magnetic susceptibility and grain size. The results show that lightness L* was dominated by the content of organic matter mainly. Largely influenced by the categories and contents of iron oxide and correspond well with magnetic susceptibility, yellowness b* could indirectly reflect the climate change and pedogenic environment in this region. At the same time, yellowness b* was dominated by the content of organic matter. Redness a* and yellowness b* were controlled by the similar climatic factors and might process the consistent color material because of some correlation. Lightness L*, yellowness b*, a*/b* could be used as good indicators of climatic change. Only by using the combination between chromatic proxies, magnetic susceptibility and grain size, we could reconstruct a reasonable reliable process of climate change and the evolution history of paleoclimate environment in the eastern part of the Northeast China Plain since Middle- late Pleistocene. Considering the 283 m of Tianhengshan core as the boundary, redness a* and yellowness b* were obviously changed. It reflects the significant change of sedimentary environment, maybe indicate that Songnen paleo- lake disappeared at 476 ka.
