grout colour for matt white 60x30 floor tiles ?

[bluesky]

hi all , just wondering if anyone has any thoughts on grout colour for matt white floor tiles - 50 m2 on whole ground floor of small bungalow ? my thoughts were white is going to get dirty ,possibly ivory or grey better ?
any ideas ?

Grey or ivory will get just as dirty, I'd go for anthracite or black.

All grout gets dirty, why not go for grey and use a grout sealer
