Changing Login Color
The Situation
I didn’t really like the default shades of
purple that Ubuntu uses for boot-up, so I wanted to change them to a pretty shade of green.
Stuff that didn't work
I tried changing the other instances of the aubergine purple by changing one
of the instances of #2c001e, but to my knowledge, that did nothing.
The Solution
To change the color of the login screen:
-
Type
xhost +local: && sudo vim /etc/alternatives/gdm3.css
You can change the editor
to Emacs or whatever you like.
-
Go to the block that begins with #lockdialogGroup, and change
the hex color from
#2c001e to whatever you want. I’m using
#0a3621.
You know how there's a screen that appears before your lock screen? That
screen was still purple, so I wanted to make that green as well.
-
Type
sudo vim
/usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.script
-
Go to the lines beginning with Window.SetBackground.
There’ll be two of them.
-
The default color on these lines is (0.16, 0.00, 0.12), which
corresponds to #2c001e.
Change this (on both lines) to whatever you want (these are ratios).
I’m using (0.04, 0.21, 0.13) .
- Type
sudo update-initramfs -u
-
That should be it!

When I boot up, there's a quick flash of purple that still appears, but
I haven't yet figured out why that is.
