@Duhproject, good to see you here, man!
And Shot's right. First thing you want to do is dial up to 8 colors under the Terminal menu.
Then you want to go over to the Project menu and select Colors.
And finally pick your colors using the RGB color sliders. I had 64 Door up on a second machine and compared my screen to the other to get A-Talk III looking fairly close on the main menus. But then I totally winged it on some sub-colors depending on what I saw screen-to-screen.
I then made some minor tweaks after visiting some other boards, like The Keep, which love ANSI.
My palette looks like this now:
And Shot's absolutely right - don't forget to go back to the Project menu and
SAVE. I made that mistake the first time around after dinking with colors for 30 minutes only to see my Van Gogh palette gone. Save that sucker and enjoy.
