Yeah but curing compounds shouldn't stain it brown. You might end up with inconsistent shades of gray. Brown stains leads me to believe a couple of possibilities.
- It was raining during the placement, and they didn't protect it post floating, so you might have light aggregate showing.
- You've got red dirt, and it was washed into the top layer because of dirty tools, rain, etc.
- they put mesh in it and just wet set it, so you might have re steel rust showing.

Here's the pic...
Where the brown and gray are divided is the exact line where the concrete was different shades of gray when it was first laid. Makes me think it's almost certain there was somehow something wrong with the concrete that turned brown.
Also, I haven't done anything to it.

Sometimes you can get aggregate with a higher iron content or if it is a truck or mixer that hasn't been used in a while rust can mix in the concrete.
If any drives on hwy 73 in prairieville by the interstate I did some concrete patching there. Several of the patches have turned brown. The concrete is fine, it just doesn't look good.
Look up bridge cote. It's extra cost but it's a paint that'll last forever.
