Book excerpt: Exuberant redhead Erik always tries his best, but he just can’t understand why he’s missing homework questions at school and messing up at soccer practice. Then one day in art class everyone notices that Erik’s painted a picture of himself with green hair! It turns out he’s not just creative, he’s color blind, too. Color blindness, also known as Color Vision Deficiency (CVD), affects a significant percentage of the population. The tendency to color-code learning materials in classrooms can make it especially hard for kids with CVD. But once Erik is diagnosed, he and his parents, teachers, coach, and classmates figure out solutions that work with his unique way of seeing, and soon he’s back on track.
