I am currently creating large map files in RM for export to a lowrance HDS live. I am using user defined RGB colour palettes between 0-100m of depth ranging from orange to blues then purple. The issue I have is when I export to the AT5 format, the colours are not the same in the HDS Live as they are represented in RM. I have previously exported maps where the colours remained the same. What am I doing wrong. Atlas version 12 or 13 on export.
