This lady below has a very neutral look. And people with this type of coloring can be very tough to color analyze.
Why? Because they are a blend of warm and cool. Almost a 50/50 blend of temperatures which creates the hard-to-determine undertone.
Even when one seems to have a perfect blend of temperatures, one usually is more dominant than the other one. The key is to figure out which is dominates, even if it is just a tiny bit.
I actually thought that because her eyes were so cool (or not warm, at least) that she would be a soft summer. But I did what I suggest to clients to do who are debating between undertones: test really cool color and really warm colors on you and see which is better, or at least, not the worst. I, of course, did it virtually on Photoshop.
I found that the warm colors edged out the cool. So my assessment is that she is a Dusty Soft Autumn. Why not a Smokey Soft Autumn? Because she is somewhat in the middle range of value, I chose the lighter soft autumn for her. But the Smokey Soft Autumn would have worked, too.
