It's easier to paint the map while in RGB mod,and after you finnish your work,just convert it back to grey/8.And each time you need to rework something on it,just convert it to RGB color before start working.ANd after you finnish...again the same.
Fabian,i dunno what you mean but....Those RGB values are right out of an experimental map_t.tga that i made.And using them,the ships are moving without problems on the water...

I found that for mapT where the greyscale values are very important....that Gimp is more accurate than PS....... originally no ships would run on my map until i changed the sea to the 28 RGB 11% which is from the default maps
I prefer to work in greyscale..because PS has trouble when converting to greyscale from RGB
