In such a case, when you don't know what colorForth is doing, I found the 
bochs debugger support very useful. If you configure with --enable-debugger 
(IIRC) you can press Ctrl-C in the console while running colorForth and bochs 
will tell you which instruction it is executing at the moment. (You will have 
to press "c" to start the simulation, see the manual for details.) Having the 
assembler generate a list file (e.g. 'as -a color.s >color.lst') helps.

When you generate the fd.img, make sure you use logo8.blk.
And could you send a copy of your .bochsrc file?
