Found it!

The dialog colours are controlled by a texture file. It's The top texture pack in KotorTool (swpc_tex_gui.erf) and it's called "fnt_d16x16b.tpc".

There's other files next to it with similar names, so I suspect the file used may change depending on the players screen res. I'm using the game at 1600x1200, so the 10x10 ones may get used if the res is lower.
