Agreeing with the others, it looks like a cross between soft gray and oatmeal.
I find these colors tough, and yet I'm really drawn to them lately! I believe I'm a muted autumn, or possibly soft autumn (not sure if there's a difference) as well. So I'm very interested in what you find out. I've been experimenting with grays lately, as I'm really drawn to them. I've always loved to wear creams and oatmeals.
I'm sorry I don't post photos, but I can describe my coloring if that might be helpful. I have light brown hair, brown eyes, and skin that tans very easily. Some say I have olive skin, but Im not sure. I tend to gravitate toward earthy tones and neutrals. But as far as earth tones go, I think the softer, muted ones look better on me. My coloring is rather low contrast as well. I know that I tend to prefer a soft plum rather than a bright purple, and a soft muted teal rather than a bright one. Other than that, I tend towards neutrals, olive, soft rusty tones, tans, etc.
I do love gray, though I'm not sure it's my best color. I have a few tops in shades ranging from light, silvery gray to dark charcoal. I often wonder if I'm neutral enough to wear both cool and warm tones. I seem to be able to wear both silver and gold jewelry.
Anyway, I didn't mean to make this all about me! I was just excited to learn of another muted autumn! I hope my thoughts help in some small way!
