I've made a new theme based on ("/usr/share/plymouth/themes/ubuntu-logo").
Simply changed all the purple into blue. I've updated the .plymouth (bluebuntu.plymouth) file and script:
Then I ran:
sudo update-alternatives --install /usr/share/plymouth/themes/default.plymouth default.plymouth /usr/share/plymouth/themes/bluebuntu/bluebuntu.plymouth 100 sudo update-alternatives --config default.plymouth
(Selected my new theme: /usr/share/plymouth/themes/bluebuntu/bluebuntu.plymouth)
sudo update-initramfs -u
The problem is the bootscreen is still showing the purple version... I even tried changing the names of all the .png files in case it's caching it based on name or something, but it doesn't work.
Is there something I'm missing?
