That is why we need to pass coloring explicitly, such that the submodule coloring decision will be made by the child process processing the submodule. Only DIFF_SYMBOL_SUBMODULE_PIPETHROUGH contains color, the other symbols are for embedding the submodule output into the superprojects output. Remove the colors from the function signatures, as all the coloring decisions will be made either inside the child process or the final emit_diff_symbol, but not in the functions driving the submodule diff.
