The name Pulcherrima was given to the B-component of epsilon Bootis (4.8 mag) by Friedrich G. W. von Struve in 1829. The Latin name translates to "most beautiful" or "loveliest," referring to its striking, contrasting colors — a bright yellow primary and a blue-white secondary star. Epsilon Boötis (ε Boo) is named Izar.
