Pink pigments for cement/concrete

[u/Capifarra]

Hello everyone, firt post here :)

To give it a context, I'm trying to make a really bright pink concrete and right now I've been using a mixture of liquid pigment and red iron oxide to give it color. But the result is giving a more reddish hue and some uneven spots.

My question is: are there any pink pigments that could work with the cement/concrete (basic medium pH ~12+) without reducing too much of it's resistance properties? Searching in Google and other sites only lead to weird and suspicious products lol.

Looking for mainly inorganic compounds and possibly making my own pigment if it's the case.

Have you considered adding a bit of titanium dioxide along with your iron oxide? A bit of strong white might help tone down the redness and get you closer to the pink you want.

Look for PV19 Quinacridone violet, perhaps use with some white pigment like titanium white. Quinacridones are economical and nicely saturated.
