//
// To set the background color:
// Insert the ESCAPE_SEQ into your string, followed by "bg12,24,36;" where r=12, g=24, b=36.
//
// To reset the foreground color (to default value):
// Insert the ESCAPE_SEQ into your string, followed by "fg;"
//
// To reset the background color (to default value):
// Insert the ESCAPE_SEQ into your string, followed by "bg;"
//
// To reset the foreground and background color (to default values) in one operation:
// Insert the ESCAPE_SEQ into your string, followed by ";"
