I'm crazy about colors.
I work with terminal emulators all the time and nothings is more deterrent to me than big wall of black & white text spitted out into my 300x100 terminal.
I want my errors red and successes green, I want numbers, URLs and paths pop out from the rest of the text, I want colored logs, compiler outputs, source code snippets... It really makes your terminal experience much more fun to use.
So let's take a look at where my obsession brought me so far.
