Just something I've noticed - I seem to mentally assign color codes to different languages. I'm curious if anyone else in IT does this.
e.g.
Ruby scripts are of course bright red. (This is probably by the gem analogy and the Ruby website's color scheme.)
Python scripts are a businesslike blue. (Again, probably the website color scheme...)
Perl scripts are an ugly shade of blue-gray. (From the Perl "onion" logo maybe? Or possibly Vim syntax highlighting.)
Bash shell scripts are charcoal-colored. Ksh is deep purple, Csh is a dim yellow. Zsh is neon green. Bourne shell is dark red, Ash is brighter red, and Dash is orange.
Java is also reddish purple, and compiled Java class files are yellow. C#/.NET is always yellow.
Wish I knew how my brain comes up with this stuff...
