Oasis montaj and Target users can modify Geosoft colour tables to create custom colour tables, as well as ZON and ITR files (which assign colours to a range of data) using the Image Colour Tool.
However, there is no button here to reverse the colour scheme using the Image Colour Tool.
You can download ready-to-use inverse colour tables for all the Geosoft standard colour tables from the Geosoft website: http://www.geosoft.com/support/updates/montajextras.asp
Just place these new files in your program "tbl" folder.
