Do you use a different brush for each blusher colour you have?

I’ve just treated myself to a fab set of mini blushers from Benefit. Can’t wait to try them all but do I need a different brush for each different colour? Otherwise they’ll surely all get mixed together?

I have separate ones for blusher, highlighters and bronzers (So I don't get muddy or shimmery where I don't want it).
I would use the same brush for all pink blushers however, just brush it over a piece of kitchen roll to wipe of the worst first.
