Changing colour profile for boot screen?

[Edelheid]

I want to change my color profile for the boot screen because the default factory setting looks really yellow. In Mountain Lion, I can achieve this by logging on my root user and changing the color display settings via System Preferences -> Displays -> Color and then after that both the boot screen and login screen share the same color display setting with my preferred custom one.

Is there a way to achieve this again under Mavericks?

First enable root user:

- Login with it using selecting "other..." in the login screen.
- Select the color profile you want.
- Log out and it should stick to the login screen. Use the same color profile for your normal user.
- Disable the root user (you should not need it afterwards)

I did these steps and it seems to stick.

edit: ugh, sorry, it seems its not sticking. Well my system asks my account login right in the beginning because i have Filevault enabled. When the system is booting the first couple seconds when the apple logo is displaying, it uses the default color profile(yellow), but then it changes to my own color profile during the apple logo and starts the desktop automatic. I dont actually see the login screen ever because Filevault forces to login straight to the desktop(i login before hard disk access). If i logout after i have visited desktop login screen will stay on my chosen color profile. Of course it will then change to another if differend user logins and uses differend color profile.

So, the whole instruction about root stuff seems not to be necessary or helping anything...

Thanks for the response.

That's what I've done and it does appear to work for the login screen, however, the boot screen at the start with the grey background and the traditional Apple logo still remains the same. The boot screen continues to use "Color LCD" default profile that's stained with yellow.

Doing this procedure worked for both the boot and login screen back in Mountain Lion, but for some reason or another it stopped working with Mavericks.

Does anyone know of a workaround for this problem of mine?
