Can anyone explain this line

Hello,
Can anyone explain this line of code
Code:
echo -e "\033[0;32m${1}\033[m"


What does '\033' do
what does [0;32m do
what does [m do?

I tried testing this line using a script
Whatever i pass as input to the script it is spit out

the developer could have simply said echo $1
why did he use all of this " \033[0;32m${1}\033[m "

Thanks,
R
