In this coloring page, we see an aged woman with a long hooked nose in a dark dress. On her head is a scarf, covering her brown tresses. She is perched atop a large mortar, which she is using to grind corn. By her side is a broom, which she is using to sweep the floor around her. To complete the scene, a small earthen pot, a basket, and a few bundles of wheat can be seen.
I would start with a base color of warm brown for the woman's skin and suggest a palette of muted earth tones for the entire illustration. For the dress, use a deep black, with an overlay of light yellow to give it a more interesting, contrasting look. The mortar should be colored a deep brown and the broom can be a light tan. For the wheat, I would suggest adding shades of gold and pale yellow. Finally, the little earthen pot can be painted a light yellow-green and the basket a darker shade of brown.
