No, no, no; you can't handwave a victory, you have to say HOW they won, when, and in what condition. Winning in Europe doesn't give you colonies! If Britain and France conquered Germany's African colonies but lost the war in Europe what is their incentive to give them back plus more? What do they get in return? You seem to be in the unconditional surrender mindset of the mid-late 20th century, peace is not normally that way.
Take it up with the OP, not me - it was his POD, not mine.
A German victory in WWI (however it's achieved) where Germany wins in Europe, but loses in Africa (as, pre-WWI POD aside, is a certainty) would surely result in Germany regaining its colonies. The Allies would have the same incentive that Germany had to sign Versailles even though they found it unpalatable - a resumption of hostilities from a losing position. They don't get anything in return - they lost the War. It's not unconditional surrender to return what the winners had at the start of the War, it's a status quo ante bellum and it's pretty much the starting position for most peace treaties. Germany wins and takes her own Colonies back - that's a given. This thread is about what else there would be after that.
