Lorenzo and his sister, Mariana, are decorating gingerbread houses. They want to make grass, so they turn their icing green by mixing yellow and blue food coloring. Both of them use the same amount of yellow food coloring, but Mariana adds less blue food coloring than Lorenzo. Whose icing is a darker shade of green?
