Here's an example of a neutral I don't use much at all, yet I appreciate it in other people's houses! Caramel is an earth shade with golden undertones; my particular "earthy" neutral has always been taupe, which has that more pink undertone, and comes across "cooler".
But here's pretty, golden caramel-- also known as buff, straw, tan or camel, more or less. Strictly speaking, caramel seems to me to have a wee bit more orange in the undertone than some of the others:

I'd enjoy caramel and golden tans, camels, but they can fight with my taupes and cocoas, etc., so I tend to like them from more afar, in my own house.
Taupe loves pinks, roses and blush, as well as blue, aqua etc., so I do like taupe. My couch is more of a deep cocoa, also compatible with taupe, b/c of a rosy-brown undertone...
But back to caramel, below. What a pretty amber this wall is-- it has "life", and I bet when sun hits it, it is very cozy. And is a natural when paired with red, many blues and greens.

The adorable "Unsellables" twins took an under 800 square foot house, and made it over, using caramel in a key spot-- the fireplace. It had been a rather overwhelming dark gray.

They re-painted it in a warm caramel, which seems so compatible with the cozy-organic, natural style they came up with for the living room--
AFTER-

Goes nicely with the tall green wainscoting they installed on the opposite wall, too. The tawny, golden-based leathers continue the warm tone set by fireplace...

Edited to add-- One caveat, that I'd like to add to the mix. Some shades, like the wall color in the magazine image at the top of the post, strike me as a little too saturated for an entire room-- unless you really like saturated colors, then bring it on. Were I inclined toward caramel myself, I'd have to have a much more watered down version, at least on walls, to be happy. "Density" of color is for me, at least as important as the actual shade....
