Hi,Helen. I've done some looking in the wordbooks. To me it was a new color name too, I must admit. Not in my list. From the look-ups it appears that it differs in definitions , which makes it all the more interesting.

I found:

: bluish gray
:having a blue very low in chroma
:Of the color of lavender; pale blue with a slight mixture of gray.
:pale blue-green
:bluish or greyish green

So quite a range of possibilities for us color minded ones. A hard to define color.
