Take those blocks up and either hide them under a flower pot or dot them about.   Replace them with new ones. Nick some from someone elses drive.  Wire brush them with a stainless wire brush.

cant do that there no flower beds  just straight driveway with nothing at sides.i seen online dye sealers do think this would work as they want it sealed any wey or if i used a gloss\wet look sealer would it hide it

I'd move the blocks about. Sealing darkens the blocks so it probably won't notice. look round the reclaim yards for the same blocks - we have one on the farm where my yard is ! I've never had any experience with dyes so I can't comment on that
