Queen Beret is not directly named after a real-life racehorse (similar to Kin'iro Ryotei). Her hair colors, eyepatch (plus color and position of said eyepatch) and portrayal as Special Week's rival in the latter's debut race indicate she is a reference to Land Ace, a mare with the same coat colors in the real-life Special Week's debut race who also wore sight-obscuring blinkers.
