This is Shell Scripting

I need the following code to stagger the display output, ask the user to enter a color of the rainbow, then dispaly the output in that single color.

#!/bin/bash

clear

for i in {0..7}

do

COLOR_VALUE="\033[1;3"$i"m Hello World"

echo -e $COLOR_VALUE

done

for i in {0..7}

do

COLOR_VALUE="\033[1;3"$i"m Hello World"

echo -e $COLOR_VALUE

done

for i in {0..7}

do

COLOR_VALUE="\033[1;3"$i"m Hello World"

echo -e $COLOR_VALUE

done

for i in {0..7}

do

COLOR_VALUE="\033[1;3"$i"m Hello World"

echo -e $COLOR_VALUE

done
