Interpreting log overlays and crossplots is standard practice in the recognition of mineral associations and lithofacies in subsurface sections. Useful features of both types of method can be combined and enhanced through the use of color as a medium of information. The three color primaries of blue, green, and red light are equated with reference axes in three-dimensional space. The resulting Briggs cube is the framework of a 3-D crossplot, where primary color axes represent logs or log-derived variables. The set of log responses from a single depth zone corresponds to a hue resulting from the color mix determined by the zone's coordinates within the cube. A strip log display of hues associated with successive zones generates a color image rendition of multiple log curves. Diagnostic coordinate values may be set for hue cell boundaries to match log classification rules, so that there are explicit meanings of color with respect to lithology or other rock properties.
