title: How to assign color to awk printf columns?
body: <p>Working on a shell script (sh, no bash) I'd like to use colors from a variable for column 1 and 3 in awk printf.
  I want to use a variable in the printf as the script uses color themes, so RED_COLOR may be a different color code than the one I assign here in the example.</p>
  
  <p>I have:</p>
  
  <pre><code>#!/bin/sh
  RED_COLOR='\033[0;31m'
  GREEN_COLOR='\033[0;92m' 
  NO_COLOR='\033[00m'
  
  
  var1=value1
  var2=value2
  var3=value3
  
  values="$var1 $var2 $var3"
  
  var1=value4
  var2=value5
  var3=value6
  
  values="$values
  $var1 $var2 $var3"
  
  echo "$values" | awk '{ printf "%-10s %-8s %-8s\n", $1, $2, $3 }'
  </code></pre>
  
  <p>$values is a list from a for loop, here, I just add them up to represent the data to be presented.
  The above outputs this list:</p>
  
  <pre><code>value1     value2   value3
  value4     value5   value6
  </code></pre>
  
  <p>I can assign the colors as code, like so for the first column:</p>
  
  <pre><code>echo "$values" | awk '{ printf "\033[0;31m%-10s\033[00m  %-8s %-8s\n", $1, $2, $3 }'
  </code></pre>
  
  <p>But how can I assign the colors to column 1 and 3, using the variable and not the color code in the printf?</p>
