You can, but I haven't found any way to do it reliably across both Windows
and Unix.

If you are in Unix, go to the terminal and run:
$ ruby -e 'puts "\e[01mBLACK \e[32mRED \e[33mYELLOW \e[34mBLUE \e[35mMAGENT=
A
\e[36mCYAN \e[37mWHITE \e[0mNONE"'

The dollar sign indicates my promt. The \e is the escape key (top left on
your keyboard, ansi character 27), then a left bracket. This \e[ is called
an escape sequence, and you can put codes after it that have special
meanings. 3#m means change the foreground, 4#m means change the background
(ie run the same code above but change the 3s to 4s.

For more about escape sequences, check out
http://en.wikipedia.org/wiki/ANSI_escape_code

There are also a ton of gems that do this (you might make one yourself, it'=
s
a fun short exercise, and will help you become familiar with how escape
sequences work).
