I would describe them as pink at the base and greenish white above that point, but either way I believe the essence comes across.
That other photo can be found here, for the curious:

One interesting detail about Aristaloe (the presumed parent of these plants) is that the flowers seem to be different colors depending on the exposure. This is not exclusive to Aristaloe, it seems to be true for various related plants. In the sun they are a sort of solid orangey pink color, but in the shade they may have much more white (or greenish white) in them, not necessarily evenly distributed.
These two pictures match the way the flowers appear in the Definitive Guide
Tiffany's plant in the second picture is clearly getting a lot of light, based on the tight, compact rosettes, and mine in the first is in full sun. Compare to these flowers presumably growing in lower light
Now this sort of complicates things with the xGasteraloe hybrids of the species. Because Gasteria flowers are typically pink at the base and greenish white near the tips. Lots of good examples on this page
Ox-Tongue (Gasteria)
like the main image for that entry
In general, I would imagine that xGasteraloe flowers would be intermediate between the two parental genera. For the Aristaloe hybrids, that would mean whitish tips, with pink bases. But depending on the light, the Aristaloe flowers may have that same pattern. Other things like the shape of the flower and the shape of the raceme (collected flowers stacked at the end of an inflorescence) might be more informative about differences there and the actual parentage involved.
