I have been working on redesigning my fursona recently. I like my witchy wolf femboy but my tastes have changed and I want something with more neutral/normal colors. I'm also changing him from a wolf to a fox. Anyways, I have the tail in the image and matching ears I got at Otakon last year from pawstar. I like the color a lot but I was wondering how hard it would be for an artist to replicate that? What would that coloration be called? I'm having a hard time finding any similar examples in furry art.
I'd describe that pattern as "agouti." Agouti is when a single hair goes from light to dark, so it is not all one color, and it produces a pattern like this. It's a common coloration pattern in wild animals. Whether an artist wants to draw that depends on the person and art style, but I think an artist could simulate it without having to draw every hair. As another commenter said, you can always simplify depending on the style you're looking for.
