When Ashley was a kid, she was legally blind. Her friends and family described colors to her in a wonderful way.
Yellow. I didn't touch anything for this, they just told me that whenever you laugh so hard you can't stop, that that happiness is what yellow looks like.
Green. I held soft leaves and wet grass. They told me green felt like life. To this day it is still very much my favorite color.
I love this list. (thx, nicholas)
