Wow, I am having a difficult time trying to figure out how to change grub menu text colors and highlight colors in 05_debian_theme. I can do this with the old 05_debian_theme format in U 10.04 or the newer one in U 12.04 but no matter what I change in 05_debian_theme, nothing takes affect. Mostly, I am trying to get rid of the gray highlight bar and replace it with a text color change to red when selected. It's as if grub in LMDE is using a file other than 05_debian_theme to configure grub's menu looks. I can get my custom background to show with no problem but I sure cannot get text color and highlight color changes. I even substituted my current 05_debian_theme with the old style that I have in U 10.04. That doesn't even do it. It does, however, do it in 12.04.
Is there something I need to know but don't know about grub theming in LMDE?
