How do I get the Mac Terminal to show the gray font color I am running on a Mac with Snow Leopard.  Up until now, the default Terminal.app has served me well.  I have installed the IR_Black theme mentioned here: http://blog.toddwerth.com/entries/show/6.

However, I noticed in a particular program that the gray font doesn't render.  In other words, it's invisible.  I ran the script listed here: https://gist.github.com/1099707 and every color shows except for COLOR_BLACK (which makes sense) and COLOR_GRAY.

There are other coworkers on a Windows box that run putty and gray shows up for them just fine on a black background.  Is there anyway to get the gray color to show up in Terminal and still have a black background? 

(If I used the Basic white-background theme, and run the colors script, then Gray just looks like a bold version of black.)
On Snow Leopard you can install the TerminalColours plugin, which lets you modify the default colours.

On Lion you get a thoroughly updated Terminal.app that lets you do this out of the box and also supports 256 colours by default.
