Try to imagine the color “mud blue.” Can’t? Well, maybe Center Stage’s new play will help. Mud Blue Sky tells the story of three flight attendants and one unexpected teenage visitor who examine their lives in an airport hotel. Their late-night conversation touches on topics such as work, motherhood, missed connections, and, of course, the prom. The play offers humor and insight from the perspective of women in their 40’s. Writer Marisa Wegrzyn has already proven her worth as a young playwright; her many distinctions include winning the Wasserstein Prize in 2009. So catch the world premiere of her latest work, directed by Susanna Gellert. The play might even help you find a new shade to paint your bathroom. (Alexa Kwiatkoski)
