Concerned about coping quality and color

[Petunia27]

Hi there,
I’m building a pool in Austin, TX and over the past 3 days the majority of the tile and coping was completed. The coping I picked out was light grey and the installed coping appears to be a variety of colors from light cream to light/medium tan. They all appear stained. Is this normal? You can see my back wall is actual grey and how the coping compares. Thanks in advance!

I don’t like that coloration nor the damage. That one in particular has excessive scratches and gouges for new coping. An in person onsite discussion with your PB is in order. He/she should agree quickly.
