emacs -nw niggles

[Richard Banach]

I use   emacs -nw  and see a couple of problems

* in tex mode, if I type   $\it identifiername$   it doesn't recognise
the second $ as closing the scope of \it ... and wants to underline
everything that follows ... i haven't found how to turn this off

* in the old days, it used the  'angry primary colors'  color scheme, which
was great for someone with poor sight like me, ... nowadays pale pastel
schemes are the default ... how can I get 'angry primary colors' back?
