Got too aggressive with steel wool on pavers, how can I make this look right?
Without seeing the "damage" I can't say for sure, but your best bet would be to try and even things out a bit, and accept that you aren't going to get a perfect finish.

Use a finer grade steel wool and try and blend the patches so you don't have a sharp transition between the colours.

You might find that leaving it over a winter will even out the colouration anyway.
