Franco-British War in Africa?

I have read that a war between France and the British Empire was quite possible, and "narrowly averted," in 1898. French military forces going east from Gabon and British forces moving south from Sudan encountered each other.

What would have happened should this have developed into a full-blown War of the Colonies?
 
Okay. I'll admit, I walked wide-eyed and bare-footed into that one.

Are there any other ways to get a non-European full-blown Colonial War between France and Britain, France and Germany, Britain and Germany, France and Spain, Portugal and Germany, Portugal and Britain, etc.?

Preferably either France and Britain or Germany and Britain.

I had an idea like this for a TL I'm in the process if writing. This could be the big POD: France and Britain fight at Fashoda, but no war occurs.
