Ubuntu 20.04 Grub colour is black and white

Question

I recently installed Ubuntu 20.04 on a dual boot with Windows 10 but from the start the grub boot loader is black and white. Now it's not much of a problem because the operating systems itself work alright but I think I would rather choose to stare at a purple screen at the start rather than a black and white one.

Thanks for any solutions .

copy paste the below in a empty text file in home directory and name the file as grub.sh.
save the file & close.

#!/bin/bash

file=/usr/share/plymouth/themes/default.grub

touch $file
echo "if background_color 66,30,53 ; then
   clear
fi" > $file

update-grub

and run the command

sudo bash grub.sh

Reboot will show you purple background for grub menu screen.
