Not exactly sure why, but the colors are supposed to affect the arrows, and they do not.

Not sure but I dont think bash accepts HEX color codes.

I am just going to leave you with my battery script:

: (Bash)

#! /bin/bash

BATTERY_DIR=/sys/class/power_supply/BAT0
ACAD_DIR=/sys/class/power_supply/AC

BARS=$( awk '{print int( 5*($0/100) + 0.5) }' ${BATTERY_DIR}/capacity)

if [ $(cat ${ACAD_DIR}/online) -eq 1 ]; then
    echo -ne "~"
fi

if [ $BARS -gt 3 ]; then
    echo -ne "\[\033[1;32m\]" #green color
elif [ $BARS -gt 2 ]; then
    echo -ne "\[\033[1;33m\]" #yellow color
else
    echo -ne "\[\033[1;31m\]" #red color
fi

for (( c=1; c<=${BARS}; c++ ))
do
    echo -ne "|"
done

for (( c=${BARS} + 1; c<=5; c++ ))
do
    echo -ne " "
done

Edit: I also have found a color script somewhere in the net that I use to choose the right color values. It is pretty useful. This is not my code:

: (bash)

#!/bin/bash
#
#   This file echoes a bunch of color codes to the
#   terminal to demonstrate what's available.  Each
#   line is the color code of one forground color,
#   out of 17 (default + 16 escapes), followed by a
#   test use of that color on all nine background
#   colors (default + 8 escapes).
#

T='gYw'   # The test text

echo -e "\n                 40m     41m     42m     43m\
     44m     45m     46m     47m";

for FGs in '    m' '   1m' '  30m' '1;30m' '  31m' '1;31m' '  32m' \
           '1;32m' '  33m' '1;33m' '  34m' '1;34m' '  35m' '1;35m' \
           '  36m' '1;36m' '  37m' '1;37m';
  do FG=${FGs// /}
  echo -en " $FGs \033[$FG  $T  "
  for BG in 40m 41m 42m 43m 44m 45m 46m 47m;
    do echo -en "$EINS \033[$FG\033[$BG  $T  \033[0m";
  done
  echo;
done
echo

The result looks like this:

Not sure but I dont think bash accepts HEX color codes.

I didn't think so either normally, but I thought that using variables might change it somehow. Thinking about it now that I'm less tired I'm really not sure why.

@ Deque- Thanks a bunch for that, will try it out. Yeah I see tons of people showing off that color script thing on all sorts of Awesome wm config threads. Here, nom on this..

EDIT: I wonder how people get that script to look like this:

Despite the fact that bash scripts can only use a few kinds of colors.
