Maroon coloured Tile Grout

I have to grout some Maroon floor tiles

Does anybody know what I can use to get the maroon colour as I can't find it in the shops.?

Can I add a dye/pigment to some white grout?

TIA

Are you sure you want maroon grout? If it's a big area you're tiling it can look pretty heavy with grout and tiles the same colour.

Usually a contrasting or complimentary colour is the norm with most tiling. However, yes, you can add pigment to the grout. Just ask your local tiling mob and they'll point you in the right direction.
