Grout Colourant, what's the best?

[Burrow 12345]

Hello Guys

I am looking for a some advice, after the tiler washing all the colour in the grey grout I have elected to use a grout Colourant.

Smart Seal do samples but unfortunately their dark grey is almost blacks and mid grey is almost white. Lots of reviews but colours are no good.

Grout Rescue colour and seal, great reviews but their RAL colours match Smarts Seals so cannot know if the mid grey will be any good as they dont do samples and Smarts Seals colours were poor.

SRP Grout Colour & Seal, ordered sample and mid grey is good however there is virtually no reviews for performance and reliability. Can anyone comment?

I am after a Product that will stand up to being in a wetroom, young kids etc etc. I don't want it failing or washing out for obvious reasons.

Thank you in advance for any advice you maybe able to give

I have used Universal grout colourant from Tradetiler a few times with different colours, it works great with new grout.
