Check out example codes for "PS1 modified lags". It will help you in understanding the concepts better.

Code Example 1

The string property is not properly closed by default
You have to add a layer of closure by adding unprintable brackeys

Example 1 : We want Hello World in green as our prompt
	Without brackeys:
    	PS1="\033[1;32m Hello World \033[00m"
    With brackeys (no text-wrapping):
    	PS1="\[ \033[1;32m \] Hello World \[ \033[00m \]"

//note : I added spaces for more clarity but they are printed if you add them

Example 2 : My prompt
	PS1="\[\033[1;32m\]\[email protected]\h\[\033[00m\] [ \[\033[38;5;215m\]\[\e[5m\]\w\[\e[25m\]\[\033[00m\] ] "

//note : I have my username and machine in green and the folder i'm in coloured in blinking orange
