This value of the white-black scale is obtained through the use of spectrophotometers when using the CIE Lab color system, which also gives values on green-red and blue-yellow scales. In estuarine/continental sediment studies, color data are still often based on Munsell Table which does not allow to obtain numeric and continuous data and which is biased by the observer’s choice.engEstuarineEnvironmentsAn attempt to develop spectrophotometry as a proxy for sedimentary studies in estuarine environmentsjournal article2013-07-19
