November Rain is a light near neutral from the Yellow Hue Family.

It is too dark to be categorised as a white or off-white.

Although it may appear that way in abundant, well balanced lighting on an exterior, in some regions.

It is lighter & likely to read cooler than Edgecomb Gray, as it sits further clockwise, away from the Yellow-Red Hue Family, by comparison.

It is also a smidge more greyed than Edgecomb Gray as it has a little less Chroma.

Classic Gray is lighter & more neutral again (more greyed) than November Rain.

But again, still too dark to be classified as a white.

It sits between Edgecomb Gray & November Rain in terms of Hue Family location.

Cooler than Edgecomb Gray but less greenish leaning than November Rain.

Have a look at them in comparison to actual whites and off-whites in the Colorography Lab at The Land of Color.

I have Samplize of November Rain, and ruled it out -- in my setting it just looked....depressing, a sad gray.

I have it in my great room which is full of outdoor light and it is perfection. The outdoor light allows the true color to show.
