How to keep the coloring in bash when using `sudo -i`?

I have changed PS1 variable in /etc/bash.bashrc to

PS1="

[033[0;37m]342224214342224200$(if [[ $? == 0 ]]; then echo "[[033[0;32m][033[01;32m]342234223[033[0;37m]]342224200"; else echo "[[033[0;32m][033[01;31m]342234227[033[0;37m]]342224200"; fi)[$(if [[ ${EUID} == 0 ]]; then echo '[033[0;31m]h'; else echo '[033[0;33m]u[033[0;37m]@[033[0;96m]h'; fi)[033[0;37m]]342224200[[033[0;32m]w[033[0;37m]]

[033[0;37m]342224224342224200342224200342225274 [033[0m]"

Which works fine with all the commands. But when I run sudo -i command, PS1 value goes to the default. To get back the color scheme, I have to run PS1=<same value> manually. Any idea what might be causing this behaviour?

Add the PS1 line to /root/.bashrc.

The reason why the color goes back to default is because when you do sudo -i, it "simulates" a root login, and in turn sources (applies) root's .bashrc, which brings the color back to the default. So adding the PS1 line to root's .bashrc should do the trick.
