No, probably purple.
To the eye, Easter's coat appears a mix of black, white, grey, etc. But in almost any light (daylight, tungsten, you name it) regardless of whether the scene is color balanced, as a digital capture, it picks up all sorts of odd colorations. And this was a mix, tungsten and daylight, and was captured with Auto White Balance, so there is a lean towards blue. However, even after color balancing, Easter's coat was reflecting and absorbing all kinds of colors, it was certainly not as neutral as it appears to the naked eye. I find this common with all of my cats with gray-ish coats.
I've found this the case with H3D shots, Canon shots, and now Phase One (remember, I've shot with all of them). Some things have to be tamed in post. It's nice to have the tools to do it.
