I've been migrating to Vim recently. It has impressive Ruby/Rails
support: indentation, intellisense for Ruby and Rails objects, a lot
of shortcuts for fast editing of Rails projects... you can even script
Vim in Ruby!

Vim also has good syntax-highlighting support. Unfortunately, the
color scheme applied through the syntax highlighting sucks. It lumps
together too many elements:

Methods, symbols, constants, class variables, instance variables,
global variables, block parameters, predefined constants and variables
--

All those are colored blue. Which completely defeats the purpose of
syntax-highlighting, to help you visually differentiate between the
various syntactical elements of the code.

Apparently, all the above (and several others)  *are* differentiated
by the Vim Ruby syntax parser. However, the default color scheme
colors them all the same. So the problem is with the color scheme.

How do I get a nice color scheme that would do a better job of
visually differentiating the various Ruby-related syntactical
elements?
