Law, I told it to Warrior, now I'm going say it to you.
You told that your team has lose because of color change. But, look the game record again. Just imagine that after warrior's first raid to my city you both would attacked DonJuan, but you both were still attacking my city. eventually - you both played vs already deadly russia, while Don was upgrading his mines and killed blue's city.
Ask yourself why don't you destroy your city as Me destroyed mine? If you did, it would be one city vs two, not two vs 1.5.
Your team has lose because of only your and warrior's mistakes, not because of color change.
