as it turns out it was an improper shade.
I'm working off another T map so know which colors are what on my new map.

It's handiest when you work in a layered file - one layer = 1 RGB value.

If you make one layer for every texture value from RGB0 through to RGB24 and assign each a color value, then you can more easily keep track of what you are doing AND more easily correct mistakes. And you can later on add extra layers if necessary, or delete unused layers ...

.psd is the format almost by default.

When you're done tweaking the .psd map_t file, then you can flatten easily in GIMP to the right type of tga format.

But best, if you have to make any corrections or additions or just wish to change your terrain, then it's easy to do so in a multi-layered file.
