# clr
#      Provides full hex color (#FF0000, #0F0, BADA55, D0A), etc) to Bash terminal
#
#      clr <HEX COLOR> outputs the control character to set the desired foreground color: 
#         clr \#FFF (or clr '#FFF') # will set the foreground white.
#      clr -b <HEX COLOR> uses the -b flag to output the control character to set the desired background color:
#         clr -b #FF0000 # will set the background red
#      clr with no parameters resets to default.
#
# The following aliases and shortcuts are also supported:
#   - cF <HEX COLOR> will return the control character to set the foreground to <HEX COLOR>
#   - cB <HEX COLOR> will return the control character to set the background to <HEX COLOR>
#   - cSet <SHORTHAND NAME> (-b) <HEX COLOR> will create a shorthand variable: cSet RED \#F00
#   - $X will reset back to normal.
#
# Usage: These return the CHARACTERS that perform these controls. As such, they're intended to be
#        either used INSIDE a string, or set to a variable that is used inside a string. For example:
#        echo "$(clr \#F00)Hello World!$(clr)"
#        -or-
#        RED="$(clr \#F00)"
#        echo "${RED}Hello World!${X}"
#        -or-
#        cSet RED \#F00
#        echo "${RED}Hello World!${X}"
#
# Installation:
#        Just add the following lines to your .bash_profile.

If you can think of a means to reduce this still further without sacrificing any of the functionality, I welcome your input!
