After the free2play patch, the game has bugged colors. It somewhat appears that the blue and yellow colors are switched. I have tried reinstall the game, but it did not help. It does not affect the game play in any way but it is quite annoying. Pictures i have attached self explains this problem.
Cool mod ! Now you can do a Blue Rush that works perfectly well (no more Yellow, though)
It looks like like colorblind mode or something
Sell it at eBay as a Ultra-Mega-Rare! xD
Can only think of a graphics driver problem, but who knows, someone actually asked for a colorblind option. ^^
Reinstalling all drivers helped! Finally Yellow rush is yellow! lol
