Thanks for the info of your experience.The orange color dust showed up on
the porch weeks before it appeared on the lawn.The blades of grass are now
this color completely all the way through.Will the lawn recover from this on
it's own?

"All the way through"? You mean, as in cross-section? Or do you mean
they're completely covered top to bottom and all the way around?

Yes, the grass will probably recover. If nothing else is dying, the
grass very likely wont die either.

the interesting thing is when it turned up on the porch...
