Yes, it's always been a problem with the CU/NGE color scheme for the H/A/M bars, some people, if not most, missed the PreCU white bars when depleted, the new color scheme wasn't clear enough, especially at some resolutions. Look at ModSource, they pretty much existed because of things like that.
You can change the color of any bar yourself though, you just need to know where to look.
Just look into your SWGEmu direcotry and find the "ui" folder, inside, open "ui_ground_hud", this is where all the H/AM bars are located, for yourself, your target and the target status overhead, it's all basic color codes such as FFFFFF for white, FF0000 for red, 0000FF for blue etc...
Open "ui_ground_hud" with notepad (Notepad++ recommended) and search for Name='AttribMod' (copy/paste it in the search), this is where your own H/A/M bars are located.
Name='Target', is where your target's H/A/M bars are located.
Name='AllTargets', is where the target status overhead H/A/M bars are located.
All three H/A/M trees will show you where the bars are actually located, you need to look for pagem='m', which shows you that "pagem" points to "m" which is where the mind bar is located "for each of the three windows (your own, your target, and the overhead status).
Basically as an example, search for AttribMod and scroll down until you see the tree with "pagem" and where the mind bar "m" is actually located, then once you find it, you can play around with color codes.
You know what, just search for Name='m' and you'll get three results, you have to change one color code in all three of them, I'm not entirely sure which one though as I haven't logged onto SWGEmu for months now, and the ui has always been a pain in the butt because of how the files were formatted.
And I'm pretty tired too right now, which makes me at least 10 times dumber.
Basically under the three Name='m' trees you'll find names such as "Current", "NormalMax", "CurrentMax", and "RecentCurrent", those are the only ones that matter, and in each of those sub trees is a color code, example, Color='#000000' or BackgroundColor='#FFFF00', the code is what you have to change, I recommend using http://www.colorpicker.com/ to pick your color code, it's pretty simple and easy and you don't have to install anything. Remember, #xxxxxx is what you have to change.
You just have to play around with each one of them, and yes, you have to restart your client after each change, it sucks I know but it's the only way. :/
Again, I'm very sorry if what I'm saying isn't clear, I haven't slept much in the past weeks and my brain feels like goo, added the fact that I haven't touched SWG since June pretty much, I feel really rusty.
