Bash Script: apply color in text

We can use the following colors' codes:

Black        0;30     Dark Gray     1;30
Blue         0;34     Light Blue    1;34
Green        0;32     Light Green   1;32
Cyan         0;36     Light Cyan    1;36
Red          0;31     Light Red     1;31
Purple       0;35     Light Purple  1;35
Brown/Orange 0;33     Yellow        1;33
Light Gray   0;37     White         1;37

And then use them like this in your script:

red='\e[0;31m'
NC='\e[0m' # No Color
echo -e "${red}Hello Stackoverflow${NC}"

Keep in mind you have to use '-e' after 'echo' and use double quote(") for text.
