Does plain concrete naturally vary in shade of grey?

Yes, genuinely — cement batch variation, curing conditions, and finishing technique can all produce subtle natural shade variation, even in concrete with no added colour — this is a normal characteristic of the material, not a defect.

This variation is generally subtle and often not particularly noticeable in everyday use — concrete’s natural, slightly varied grey tone is part of its authentic character rather than something to expect as perfectly uniform.

If perfectly consistent colour genuinely matters to you, this is exactly the kind of consideration that might point toward a specifically formulated coloured concrete instead, where colour consistency is more actively controlled.
