Colors of Morality (what's the right trope here?)

The colors of morality group left me kinda wanting a clarification. I'm working an alternate history story about WWII. Though normally, and under historic conditions, rightly, is depicted as a black and white affair, in my story, the German military overthrow Hitler and tries to make peace with the Allies, only to be rebuffed.

The Nazis are clearly evil, but just as the Wehrmacht colluded with Hitler, The Allies so to collude with Stalin and were willing to give half of Germany and half of Europe to the Reds. The difference is that the Wehrmacht STOPS working with Hitler, even as the Allies try to bind Stalin ever closer to the Anglo-American alliance. So the Germans can claim the moral high ground, stating whatever they did that was wrong, they are the only force that can save Eastern Europe from Communism, the only people who can guarantee that millions of Axis prisoners will not be left to die in Soviet Gulags, and that they are now fighting simply for the right to go home.

So essentially, the Germans become the good guys by default, as the Allies have disgraced themselves by associating with the Georgian psychopath. In our world, Hitler was never overthrown, so none of this matters. But in the story a third option becomes available, one the Allied leadership is desperate not to take: an honorable peace with a Denazified Third Reich.

I can't figure out if this is Black and grey, White and Grey, or Grey and Grey, but it does involve the gravity of moral right passing from the Allies and onto the Germans, which is more degradation of the Allies than redemption on the part of the Germans. Any help is appreciated.

I'd wager Grey vs Gray.
