Common mistakes when mixing mustard yellow

Mustard is yellow pulled toward brown and green at the same time, and most painters only pull it toward one or the other, landing on a plain gold or a dull olive instead. A small amount of both a red-brown and a green-black earth pigment, added to a strong yellow, gets the double shift right. Go slowly: mustard turns to olive green fast if the darkening pigment overwhelms the yellow.

Why the three mediums differ for mustard yellow

  • acrylic carries a 10% value shift on drying in Chromilla's model (dries slightly darker and a touch warmer), so the acrylic mix is predicted to dry to #AF8B28.
  • oil dries true to color in Chromilla's model, so the oil mix is predicted to dry to #BF9A2F.
  • watercolor carries a 8% value shift on drying in Chromilla's model (dries slightly darker and a touch cooler), so the watercolor mix is predicted to dry to #AF8E2D.
  • In watercolor the paper is the white, so lighter versions come from adding water rather than white paint.
