Changing Color Palettes

Specify color fills for logs and traces in seismic, logs, cross plots, models, and more using the Color Palette dialog box. Color schemes can be loaded from stock color palettes that ship with GeoSyn, or from color templates you save in the GeoSyn Working directory with a .pal extension. Templates can be quickly applied to any synthetic and can be shared amongst GeoSyn users.

Color schemes can also be configured for the current synthetic without creating a template and can be automatically saved with individual GeoSyn files.

To automatically apply a color scheme to all new synthetics, apply it to the current synthetic then update the import defaults file with the current synthetic options. For details, see Related Topics below.

When working with models and certain types of crossplots, you can drag the min max color nodes that appear at the top and bottom of the histogram to tighten them to the desired amplitude range so that a fuller color spectrum is displayed in GeoSyn. This option isn't available for cross plot properties with a depth-based color reference type, or for logs, as typically a certain color represents a certain log value and is related to lithology.

To change color palettes:

  1. Open the Edit color palette:
    • Well Properties: Log Properties, select Edit adjacent to the Infill display ().
    • Model Properties dialog box, select Edit adjacent to the color display ().
    • Seismic Properties dialog box, select Edit adjacent to the Color underlay display ().

The Edit color palette dialog box appears. The top and bottom of the color bar represent the fixed extremes in the data values of the selected log or trace. Nodes along the display bar associate a color to a particular data value.


  1. Choose a palette:
  • Copy a stock palette drop-down list
  • Load import a previously saved custom palette .
  • None remove all colors

To create a custom color palette:

  1. Creating a custom color bar can be done in several ways:
  • Drag and drop color on existing node.
  • Drag and drop color on the color bar. GeoSyn creates a corresponding node for each color you drop.
  • Create a custom color
  1. Type a unique name for this color configuration in the Palette Name box then click Save to save it in the GeoSyn Working directory.
