Rendering of trains - use colors with contrast

[hajo4]

Currently, each train is assigned a color according to its position in the list of AIs.
So, in theory, an AI could be recognized by its color.
But in practice, this is hard to do.
Also, trains can have very similar colors in matches,
making it hard to see which train is which AI.

I suggest to use just a short list of colors for the trains of a match,
e.g. red/yellow/green/blue.

Also, use these colors for the names of the AIs
in the result-messages after the match.

Actually, the trains use colors according to a random value, which uses the AI's name as the seed value. So in each match an AI should always have the same (random) color.

I agree that the colors are too similar sometimes. However, a list of colors might make this even worse - then every now and then, two AIs wouldn't just have similar colors, they'd have the exact same colors.

I'm open for suggestions, but at the moment I think these slightly different colors are better than risking to have exactly the same colors...

I meant, the first AI in the match gets red, 2nd gets yellow, 3rd gets green, 4th gets blue.
Really simple...
