+    ANSI Console Color Codes
+      8 Colors Foreground
+      The most basic terminals have a set of 8 different colors:
+
+      Black: \u001b[30m
+      Red: \u001b[31m
+      Green: \u001b[32m
+      Yellow: \u001b[33m
+      Blue: \u001b[34m
+      Magenta: \u001b[35m
+      Cyan: \u001b[36m
+      White: \u001b[37m
+      Reset: \u001b[0m
+
+      16 Colors Foreground
+      Most terminals, apart from the basic set of 8 colors, also support the "bright" or "bold" colors. These have their own set of codes, mirroring the normal 
+      colors, but with an additional ;1 in their codes:
+
+      Bright Black: \u001b[30;1m
+      Bright Red: \u001b[31;1m
+      Bright Green: \u001b[32;1m
+      Bright Yellow: \u001b[33;1m
+      Bright Blue: \u001b[34;1m
+      Bright Magenta: \u001b[35;1m
+      Bright Cyan: \u001b[36;1m
+      Bright White: \u001b[37;1m
+      Reset: \u001b[0m
+
+      Background Colors
+      The Ansi escape codes let you set the color of the text-background the same way it lets you set the color of the foregrond. For example, the 8 background 
+      colors correspond to the codes:
+
+      Background Black: \u001b[40m
+      Background Red: \u001b[41m
+      Background Green: \u001b[42m
+      Background Yellow: \u001b[43m
+      Background Blue: \u001b[44m
+      Background Magenta: \u001b[45m
+      Background Cyan: \u001b[46m
+      Background White: \u001b[47m
+      With the bright versions being:
+
+      Background Bright Black: \u001b[40;1m
+      Background Bright Red: \u001b[41;1m
+      Background Bright Green: \u001b[42;1m
+      Background Bright Yellow: \u001b[43;1m
+      Background Bright Blue: \u001b[44;1m
+      Background Bright Magenta: \u001b[45;1m
+      Background Bright Cyan: \u001b[46;1m
+      Background Bright White: \u001b[47;1m
+
+      Decorations
+      Apart from colors, and background-colors, Ansi escape codes also allow decorations on the text:
+
+      Bold: \u001b[1m
+      Underline: \u001b[4m
+      Reversed: \u001b[7m
