Change the default colormap used to fill contour maps in Surfer

Changing the default colormap requires a Color Spectrum (CLR) file name and path.  To save a preset or custom colormap to a CLR file, click Save in the Colormap Editor.

1. Click File | Defaults.
2. In the Settings section, expand the Map Contour section.
3. Select cFillFgClr.
   1. In the Setting value field, enter the full file path to the CLR file you wish to use. For example: C:\Program Files\Golden Software\Surfer\Rainbow6.clr.
   2. Change the Setting persistence to Always reset.
      
4. Click OK.
5. Click Yes to save the changes to the Surfer.set file.

To return Surfer to the original default, follow the same steps but enter Internal Default in the Setting value field.
