Description: This picture uses only two inks, pink and blue. So where do the soft shades and the purple come from? Halftone: each ink is laid down as a grid of tiny dots. Where the image is dark, the dots grow fat and merge; where it is light, they shrink to specks. Your eye blends them, and where pink and blue overlap, purple appears.
