From pinking shears to pink ribbons, the color pink is associated with fashion and femininity; perhaps no other color has as much social significance and gender association. The fascinating exhibition “Think Pink” explores the history and changing meanings of the color as its popularity ebbed and flowed in fashion and visual culture from the 18th century to the present day. An interdisciplinary show drawing from across the MFA collections, “Think Pink” juxtaposes clothing, accessories, graphic illustrations, jewelry, and paintings to shed light on changes in style; the evolution of pink for girls, blue for boys; and advances in color technology. “Think Pink” includes a selection of dresses and accessories from the collection of the late Evelyn Lauder, who was instrumental in creating an awareness of breast cancer by choosing the color as a visual reference. The opening of “Think Pink” in October coincides with Breast Cancer Awareness Month, when the MFA will be illuminated in pink.
