Question about Coloring

[Yaakoub El Khamra]

Greetings
I have a system of equations that I am solving with SNES on a DA, and
the coloring is almost exactly as the one I would get with
DAGetColoring but different in a very small and identifiable number of
locations. Is there a way to modify the coloring I get from
DAGetColoring directly as opposed to running MatGetColoring? Or should
I register my own coloring using MatColoringRegisterDynamic? Any
ideas/suggestions/examples are greatly appreciated.


Many thanks in advance.
