[Note: this answer works for CentOS. Fedora should be similar]

You add your own functions to the boot process either in /etc/rc.d/rc.local or as scripts in /etc/rc.d/init.d/ (see man chkconfig to see how the runlevel files are set up). Include /etc/rc.d/init.d/functions in your script and environment variables will be set with commands to set the following colours:

SETCOLOR_SUCCESS # green
SETCOLOR_FAILURE # red
SETCOLOR_WARNING # yellow
SETCOLOR_NORMAL # normal

So you added the following to rc.local:

. /etc/rc.d/init.d/functions
$SETCOLOR_FAILURE
echo "Hello world!"
$SETCOLOR_NORMAL

You will get a red "Hello world!" in your boot sequence. For other colours, you would need to look up the ANSI escape sequences, which you can find on the Web easily enough.

You can set the colours in /etc/sysconfig/init.

You need to know the escape sequence corresponding to each colour.

Say I want to make a name that I have added to the boot sequence

Blue

Can you give me an example of what to do?

Thanks

You put something like this in the init script

#! /bin/sh

SETCOLOR_BLUE="echo -en \\033[0;34m"

# Source function library.
. /etc/rc.d/init.d/functions

$SETCOLOR_BLUE
echo "I'm blue"
$SETCOLOR_NORMAL
echo "I'm back to normal"
