1965 273 Plug Wire color????

I just looked through my notebook and I found a Aug. 66' Hot Rod Magazine article with black and white photos. I looks to me like the wires were black with different colored ends. My guess would be black with orange boots.
The car that was pictured is a 66 Dart with California Emissions. (CAP) I'll see if I can scan or photograph the picture if you wish. tmm
