Console Output Color

Briefly about how to make color output of text for your console program or script, as well as to supplement it with other design elements. Actually, you can assign text color, background color below it, make the text bold, underlined, invisible and even blinking.

The pattern for use in modern command shells and programming languages ​​is: \ x1b [ ... m . This is an ESCAPE sequence, where \ x1b denotes an ESC character (decimal ASCII code 27), and instead of "..." values ​​from the table below are substituted, and they can be combined, then you need to list them separated by a semicolon.

attributes
0	normal mode
one	fatty
four	underlined
five	flashing
7	inverted colors
eight	invisible
text color
thirty	the black
31	red
32	green
33	yellow
34	blue
35	purple
36	blue
37	white
background color
40	the black
41	red
42	green
43	yellow
44	blue
45	purple
46	blue
47	white

Now a few examples. All this can be tested by entering the echo -e " " in the echo -e " " console window.

Input	Result
\ x1b [31m Test \ x1b [0m
\ x1b [37; 43m Test \ x1b [0m
\ x1b [4; 35m Test \ x1b [0m

')
Note that in all three cases, after the word Test, there is a sequence \ x1b [0m , which simply resets the style to the standard one.

Comprehensive use case:

\ x1b [1; 31m String \ x1b [0m with \ x1b [4; 35; 42m different \ x1b [0m \ x1b [34; 45m styles \ x1b [0m \ x1b [1; 33m clearance \ x1b [0m

Good coloring of the output often greatly facilitates the perception of information. So try and experiment.

PS Also about this and some other can be read in man console_codes . Thanks Riateche for the hint.
