As I wrote in Chapter 14 of my book, Pro Bash Programming:
"Traditionally, screen manipulation is done through the termcap or terminfo database that supplies the information necessary to manipulate any of dozens or even hundreds of types of terminal. The shell interface to the database is an external command, tput.

On some systems, tput uses the termcap database; on others (mostly newer systems) it uses the terminfo database. The commands for the two databases are not the same, so a tput command written for one system may not work on another.

On one system, the command to place the cursor at the 20th column on the 10th row is:
Code:
tput cup 9 19
On another system, the command is:
Code:
tput cm 19 9
These commands will produce the correct output for whatever type of terminal is specified in the TERM variable. (Note: tput starts counting at 0.)

However, the plethora of terminal types has, for all intents and purposes, been reduced to a single, standard type. This standard, ISO 6429 (also known as ECMA-48, and formerly known as ANSI X3.64 or VT100), is ubiquitous, and terminals that do not support it are few and far between. As a result, it is now feasible to code for a single terminal type. One advantage of this homogeneity is that the necessary coding can be done entirely within the shell. There's no need for an external command."

The following codes gives you what you need:
Code:
## bold
printf '\e[1m'

## red foreground
printf '\e[31m'

## red background
printf '\e[41m'

## underline
printf '\e[4m'

## colours
  black=0
    red=1
  green=2
 yellow=3
   blue=4
magenta=5
   cyan=6
  white=7

tput

tput(1) 						      General Commands Manual							   tput(1)

NAME

       tput - query terminfo database

SYNOPSIS

       type] capname...

       type] capname [parms...]

DESCRIPTION

       The  command  uses the database to make terminal-dependent capabilities and information available to the shell (see terminfo(4)).  The com-
       mand outputs a string if the attribute (capname) is of type string, or an integer if the attribute is of type integer.  If the attribute is
       of type boolean, simply sets the exit code for TRUE, for FALSE), and produces no output.

   Command-line Arguments
       The command recognizes the following command-line arguments:

	      Indicates the type of terminal.
			     Normally this flag is unnecessary because the default is taken from the environment variable

	      capname	     Indicates the attribute from the database.  See terminfo(4).  In addition, the following capnames are supported:

				  Echo the clear-screen sequence for the current terminal.

				  Echo the initialize sequence for the current terminal.

				  Echo the sequence that will reset the current terminal.

	      parms	     If the capname takes optional numeric parameters, the parms will be placed in the string output by

	      The	     capnames  are  read  from stdin and multiple capnames are allowed.  Only one capname is allowed per line when reading
			     from stdin.

EXTERNAL INFLUENCES

   Environment Variables
       determines the locale to use.  This overrides settings of other environment variables.

       determines the language to use for messages.

       determines the terminal type if the option is not specified.

EXAMPLES

       Echo clear-screen sequence for the current terminal.

       Print the number of columns for the current terminal.

       Print the number of columns for the 70092 terminal.

       Set shell variable to stand-out-mode sequence for current terminal.

       This might be followed by a prompt:

       Set exit code to indicate if current terminal is a hard copy terminal.

       Clear the screen, move the cursor to line 10, column 20 and turn on bold.

RETURN VALUE

       If capname is of type boolean, then the exit code is set to for true and for false.

       If capname is not of type boolean and fails, an error message is printed, and exit code is set to one of the  following	depending  on  the
       failure:

	      The capability name is of type integer and does not exist.
	      Usage error.
	      Unknown terminal type.
	      Unknown capability name.
	      An error occurred.

       If  the	exit  code  is a is printed if a capability name of type integer is requested for a terminal that has no entry for that capability
       name in the database (such as
