While this was released as part of a line of brunette colors, we definitely consider this color an auburn.
Let’s break down the color code to make the case!
FS = this is a syrup shade, so lots of highlights will be all over this wig, including the nape!
26 = a medium golden blonde with hints of copper in it, often called “butterscotch blonde;” this is the highlight shade
31 = a medium coppery auburn color with a little light golden brown mixed in; this is the base shade
S6 = the roots are shaded a darker color to mimick natural regrowth, this time a #6, which is a medium-dark brown
Salted caramel is the rooted version of the popular Caramel Syrup color (FS26/31 without the S6 in the color code). The original can be seen below on Elle.
