#!/bin/bash
if [ ! $1 ]
then
echo "no param"
else
set FAV_COLOR=$1
echo "My fav color is ${FAV_COLOR}"
fi

>favcol.sh blue
My fav color is FAV_COLOR=blue

Remove set
.
FAV_COLOR=$1
echo "My fav color is ${FAV_COLOR}"
Or if you want to set it so that it is available to subsequent programs run in the shell:
export FAV_COLOR=$1
echo "My fav color is ${FAV_COLOR}"
The export
keyword is described fairly well here.
