   4 # Usage:
   5 # 1. Save as `vt-color-scheme.py`
   6 # 2. Make executable
   7 # 3. Go to https://terminal.sexy and make your own color scheme
   8 # 4. Export as JSON (easier to work with) and edit TANGO_SCHEME
   9 #    with the colors you chose
  10 # 5. Run this script (redirect to text file if it's easier for you)
  11 # 6. Paste the output as boot option in Lilo / Elilo etc.
