Abstract:The color display of seismic data is of great significance,as is well known.But haw is the colaur display realized an our equipment used,This paper offers a scheme far it's implementation,in respect to hardware,we have designed faur circuit boards and a device which can change colaur filters automatically,in respect of software,we have made three prog ram,and made due modification of GS-3410 platting program used in 1704 computer, The schem0 may pravide 14 colour codes and display nine kinds of cross sections such as bright spot,interval velacitY, pseudo velocity Iog and instantaneous information,etc.
