Colorblind help

As far as I know, ships don't appear on the FSS screen. Changing the HUD colours also changes the colour of other elements on the screen , for example the colour of friendly/enemy ships.

And don't *sigh* at me

*double sigh*!!!

The HUD changes color when you change modes, lol...

I would agree that the colour difference between the analytical and combat mode is less important since those bars are already different (curved or straight) in each.
That said, the blue is not a random colour, contrasting with the orange and appears to be the same as the shield-rings or other GUI elements or text.
I can imagine a choice between high contrast GUI (default) and a few single color variants (although the scanner and IFF colours remain an issue) best suited for different visual deficiencies.
