Prof, the Dulux code for the above spectrum that mech posted.

620-04912 vivid white

Ah.yes..I've seen that Vivid White..Thanks very much for that.

Please note, I have already tried adding pure aluminium paste. At the moment though controlling the reflective balance is proving difficult. Mech has some of my mix results.
The fundimental problem is a physics one, where the blue end of the spectrum scatters more readily(tis why the sky is blue no less), although the spectral response of pure ali is fairly flat the combination of TiO2 and Aluminium creates a different spectral response. ie a blue push result. Just adding tints hasn't so far been so succesful where the result is fairly lumpy.

Thanks for that info. Smokey Joe..I take it that this different spectral response is caused when you combine the aluminium and Ti02 together in a mix.?.
I wonder if this would still occur when the Ti02 is layered on top of the AL.?

I think we are at the point of looking for a third element, natural tints aren't really it either as most don't push in the ideal way.

I don't think the addition of WOP (White Opal Pearlescence for those who are not familiar with the term) would help either, since If I remember correctly, it has a slight blue push also..
MMan might know more about that..
