How to reverse the colours in a Geosoft color table (*.tbl)

Objective:

I would like to reverse the colors in a predefined color table. 

Resolution:

To reverse a colour table (*.tbl):

1. Import the colour table in Excel (File menu > Open).
2. Browse to the folder where the *.tbl is saved, select All Files (*.*) as the file format and select the *.tbl file.
3. Use the Excel Text Import Wizard to import the *.tbl into separate columns.
   If you're editing a colour table file from the C:\Program Files\Geosoft\program_name\tbl directory it is recommended that you create a copy of the file so that the original will be retained.
4. In the first empty column, place a 1 beside the first row of values, a 2 beside the second row, and a 3 beside the third.
5. Highlight these 3 cells, click and hold the bottom right corner of the selection and drag it all the way to the bottom (your cursor will change from a fat white cross to a skinny black cross).  Excel will fill the series for this column.
   
6. Highlight all of these new values, right-click > Sort > Sort Largest to Smallest.
7. Choose Expand the selection and click Sort.
   All columns should now have been flipped with the newly created column as a reference for sorting.
8. Delete the new column that was added.

To save the changes as a new *.tbl:

1. From the File tab, select Save as.
2. Type in a File name and enter the extension as *.tbl.
3. Set Save as Type to Text (Tab Delimited) click Save.
4. In Windows Explorer, change the file extension from *.tbl.txt to *.tbl.

To display a grid with the new colour table:

1. Double-click the grid group in the View/Group Manager Tool for the map.
2. In the Colour Tool, click Load from File.
3. Browse to and select the new colour table you saved.
4. Click OK on the Colour Tool dialog box.
