This prompt is color-scheme-able.  You can invoke it thus:

  prompt fire [<fire1> [<fire2> [<fire3> [<userhost> [<date> [<cwd>]]]]]]

where the parameters are the three fire colors, and the colors for the
user@host text, date text, and current working directory respectively.
The default colors are yellow, yellow, red, white, white, and yellow.
This theme works best with a dark background.

Recommended fonts for this theme: nexus or vga or similar.  If you
don't have any of these, the 8-bit characters will probably look stupid.
