Default white concrete colorant

I'm looking for ideas for a white or slightly tan colorant for the last layer of ferrocement. (Ferrocement is a thin mixture of high psi low water cement layered over stucco lath.) I think titaniun dioxide will work well - if I could find it at a reasonable cost. Any ideas on where I can find it or maybe you have another idea that's better. Latex paint can be mixed with the mortar with limited results.

Do we have any mudders on this site?

Not sure of your application but white cement (expensive) and silica sand (also expensive) will give you white.

Yes, white sand is unavailable locally, but the cement is available and very pricey. Thanks

Why not white wash it? I've seen it on straw bail houses and it looks great, pretty sure they just used lime and water.

I prefer something permanent. I could mix the lime with the last coat. That may fit the bill.
