I suspect the problem is with the terminfo/termcap setting on the
solaris box. If I udnerstand you correctly, you get good colors on the
solaris box if you run emacs directly in a terminal on that box, but if
you ssh into that box, you only get limited colors? 

Check to see if you get the same TERM setting in both cases. I suspect
that solaris either isn't recognising the TERM setting that is
initialised when you connect via ssh and is either defaulting to a
related TERM entry that only supports limited colors or something
similar. I remember exactly this type of problem when color consoles
were first introduced into Linux. If you ssh to a remote system that
wasn't a Linux box, you wouldn't get any colors. This was because at
that time, the terminal setting was linux-color console-color and remote
non-linux systems were not able to recognise the terminal type, so they
would default to something without any colors or with more limited
capabilities. 

The solution was to add the terminfo entry from the linux box to the
remote terminfo database or set the TERM variable to something that the
remote system recognises and which provides full color support.
