# AA (attributes) : 00|01|03|04|05|07|22|23|24|25|27
# FF (foreground) : 38;05;color
# BB (background) : 48;05;color
# color           : 000-255

# Attributes meaning
# 00  Reset
# 01  Bold
# 03  Italic
# 04  Underline
# 05  Blink (doesn't work when a background is set)
# 07  Reverse (swap foreground and background)
# 22  No Bold
# 23  No Italic
# 24  No Underline
# 25  No Blink
# 27  No Reverse

#    echo -e "\033[38;05;226mHello, World"
# -> Hello world in bold blanking yellow:
#    echo -e "\033[01;05;38;05;226mHello, World"
# -> Hello world in bold yellow with a red background:
#    echo -e "\033[01;38;05;226;48;05;196mHello, World"
