ANSI attribute codes

An ANSI escape sequence has the format ESC[X;Ym, where ESC is the escape character (octal 033). X and, optionally, Y, is one of the following escape codes:

• attribute codes
  • 00 = none
  • 01 = bold
  • 04 = underscore
  • 05 = blink
  • 07 = reverse
  • 08 = concealed
• text color codes
  • 30 = black
  • 31 = red
  • 32 = green
  • 33 = yellow
  • 34 = blue
  • 35 = magenta
  • 36 = cyan
  • 37 = white
• background color codes
  • 40 = black
  • 41 = red
  • 42 = green
  • 43 = yellow
  • 44 = blue
  • 45 = magenta
  • 46 = cyan
  • 47 = white

For example, the sequence ESC[1;32myafc rulesESC[0m will be the string yafc rules in bright green, after which the attribute is restored to normal.
