"Yellow and the Perception of Reality" by Maureen McHugh is a science fiction story about a woman who delves into the mystery of why and how her twin sister, a physicist, has been brain damaged in a lab accident in which two of her colleagues died. I wear yellow when I go to see my sister. There's not a lot of yellow at the rehab facility; it's all calm blues and neutrals. I like yellow--it looks good on me--but I wear it because Wanda is smart and she's figured it out. She knows it's me now when she sees the yellow.
