ANSI Colors List

ANSI Color table

Intensity	0	1	2	3	4	5	6	7
Normal	Black	Red	Green	Yellow	Blue	Magenta	Cyan	White
Bright	Black	Red	Green	Yellow	Blue	Magenta	Cyan	White

Use "\e[0;34m" (or "\x1b[0;34m") for blue, "\e[1;34m" for light blue.
Vary first number: 1=alt_color, 3=bold, 4=underline, 7=invert, and so on.

Using with printf

You can output colors to a shell using printf as per this example:

$ printf "My favorite styles are \e[0;31m red \e[0m , \e[1;32m bold green \e[0m and \e[7;44m inverted blue \e[0m \n"

Here are the full color codes to copy:

ANSI codes
Black	\e[0;30m	White	\e[1;37m
Brown	\e[0;33m	Yellow	\e[1;33m
Gray	\e[0;37m	Dark Gray	\e[1;30m
Blue	\e[0;34m	Light Blue	\e[1;34m
Green	\e[0;32m	Light Green	\e[1;32m
Cyan	\e[0;36m	Light Cyan	\e[1;36m
Red	\e[0;31m	Light Red	\e[1;31m
Purple	\e[0;35m	Light Purple	\e[1;35m

Remember that varying the first number ("\e[0;32m") can result in some cool effect like bold (3), underline (4), invert with background (7), crossed-out (9) and so on.
