Color, Character and Zero-Phaseness
“The total quantity of information recorded on a typical seismic line is enormous. It is virtually impossible to present all this information to the user in a comprehensible form.” This quotation from Balch (1971) is even more true today than it was in 1971 and color has become an important contributor to the problem’s solution. The human eye is very sensitive to color and the seismic interpreter can make use of this sensitivity in several ways. Taner and Sheriff (1977) and Lindseth (1979) were among the first to present color sections which demonstrated the additional information color can convey. Of equal importance is the increased optical dynamic range of a color section compared to its black and white variable area/wiggle trace equivalent. Both these properties are of great importance in stratigraphic interpretation.
