Have some here not unlike her... most are 3/4 AN - 1/4 SM, a few are 1/2 SH, 3/8 AN, 1/8 SM.
Charolais, Simmental, or Gelbvieh with color dilution/inhibitor genes could all give you an 'off' color similar to that... suppose Braunvieh, Aubrac, and some original color Tarentaise could probably bring it, too.
