What is a dull yellow or yellowish brown colour?

Colours that are dull, dirty, muddy, or yellowish brown evoke feelings of gloominess, sickness, and decay. However, these earthy hues also connect us to the natural world and have their own quiet beauty. In this article, we’ll explore the characteristics of these colours and examine some real-world examples.

Defining Dull Yellows and Browns

First, let’s clarify what exactly constitutes a dull yellow or yellowish brown colour. These colours can be described as:

  • Muted, greyish, and unsaturated – They lack the vividness of pure yellow and tend to be mixed with grey or brown.
  • Murky, muddy, and dirty – They evoke dirt, soil, rust, and other earthy elements.
  • Gloomy, sickly, and decayed – They remind us of illness, rot, and death. But they can also represent nature’s life cycles.
  • Warm and mellow – While muted, they are still warm hues on the yellow-orange side of the colour wheel.

Specific colours that fall in this category include ochre, mustard, khaki, amber, buff, goldenrod, tan, and dingy lemon yellow. When describing these colours, words like dirty, drab, faded, weathered, aged, sepia, grimy, and jaundiced are often used.

The Psychology of Dull Yellows and Browns

Why do these colours evoke such visceral reactions in us? Colour psychology suggests some reasons:

  • They resemble bodily fluids like phlegm, vomit, urine, and pus, triggering disgust.
  • They remind us of decaying plant matter, evoking thoughts of rot and death.
  • As earthy, natural colours, they represent imperfection and austerity.
  • Their mutedness can suggest depression, sickness, and gloom.

However, these colours also relate to the natural world, evoking images of soil, rocks, driftwood, and autumn leaves. There is beauty in their realness, warmth, and organic imperfections.

  • Mustard yellow is associated with poison bottles and toxic chemicals like sulfur mustard.
  • Jaundiced skin, like that of The Simpsons characters, evokes illness and dark humor.

Mixing Dull Yellows and Browns

You can mix your own dull yellow and brown colour variations by combining paint pigments. Try blending:

  • Yellow ochre + burnt umber = golden brown
  • Yellow ochre + raw umber = muted mustard
  • Cadmium yellow + burnt umber = rusty amber
  • Lemon yellow + raw umber = dirt yellow

Adjust colours by adding more yellow for brightness or more umber/brown for earthiness. Adding a touch of black or grey will also mute and darken a colour.


Dull yellows and yellowish browns evoke feelings of gloom, sickness, and earthiness. But they also connect us to the natural world and have distinct beauty. These versatile, familiar colours continue to make an impression across military garb, industrial equipment, fine art, food, and nature.

So next time you encounter a mustard yellow wall or amber glass bottle, consider the nuanced symbolism and psychology behind the colours. While muted, they still inject a warm, organic life into their surroundings.
