Possible to increase brightness or change color of auto-pilot lines?

hum well you can change your base color when tweaking your race at the beginning of a new game, other than that ... I don't know

but there's also a few things you can try before changing those colors...

first and foremost depending on you specific screen and graphic card and settings, the actual color shown can differ by quite a bit

For example, if you use AA (antialiasing located ni video options) and if you have an Nvidia graphic card, you have to know that by default, Nvidia doesn't correct the gamma of its Antialiasing (this can be corrected though) so that's a first thing...

Your screen may not be well adjusted for colors too, most screens are setup by constructors so that you think colors on that screen are better, despite the fact that they are not accurate and often too much blue, too much green and/or too much red...

Also If the nebulae option is turned all the way to the max, the background color of the nebulae may make things more difficult to see. No nebulae is better in this case...

I'm just hinting at things here and there just so you know, but in any case it's true that terran autopilot lines don't really stand out, so maybe just changing their colors to brighter ones will do the trick for you...

Thanks for the suggestions!    I'll have to wait until I get home, but I'm running the game on a compaq laptop with not-particularly high specs (2.4ghz P4, integrated graphics and 512MB RAM).  I'm impressed that it runs at all, let alone runs fairly well.

Re: re-setting your race's color, is it possible to do this from within the game I'm already playing, or will I have to wait until the next game?

new game only I'm afraid
