The problem with the current HUD color hacks for the PC is that
all the colors change, even those which should not change color (like ship colors on the radar: red for enemies and green for friends).
Many players have been begging for "proper" customizable HUD colors for at least 2 years, yet FD hasn't done it. I suspect this is really hard to do, probably because the colors are "baked into" the HUD graphics; that is, the UI elements are loaded from pre-colored (orange) bitmaps. That would mean that to do this properly would require FD to completely redo all the HUD graphics and related drawing code.
To offer the PC-style HUD color hack would require them to create some sort of UI to enter RGB values, or allow the user to pick from a limited number of presets.
I've stuck with the orange, because having the other (non-orange) UI elements change color is unacceptable to me.
Not sure if orange is a color that is problematic for color-blind people...
Actually, orange is ideal for the most common type of color blindness (red/green).
