The colour of fog is basically the result of the refraction of water droplets in the air and light. It is most often greyish-white or whitish in colour, because the water droplets scatter the sunlight, which is then evenly distributed. However, this colour can vary depending on the weather conditions and the pollution in the environment. For example, morning fog more often appears white in clean air, while urban fog may be slightly browner or more yellowish due to pollution.
When sunlight filters through the fog, it can produce different shades. Depending on the time of day, the fog can turn orange at dawn and dusk when the sun is at a low angle. Evening fog can often be bluish due to less intense sunlight. The colour of the haze therefore changes dynamically depending on environmental conditions and lighting.

What is the colour of fog?
The colour of the fog is usually grey or white, but it can vary depending on atmospheric and lighting conditions. In the presence of sunlight or other light sources, the fog can sometimes take on a pale yellowish, pinkish or bluish tint.
What does the colour of fog depend on?
The colour of fog depends on several factors. These include the size and density of water droplets in the air, the time of day, and the pollutants in the air. Fog often looks white or grey because the sun's rays scatter on the tiny water droplets. When the sun is low in the sky, the fog can take on yellowish or orangey tones, similar to the colours of sunsets or sunrises. In addition, if there are impurities in the air, such as smoke or dust, these can also affect the colour of the fog, often resulting in darker or brownish hues.
How is the fog colour colour mixing possible?
The mixing of fog colour is based primarily on the mixing of light colours, as fog itself is made up of tiny water droplets or ice particles in the air that scatter light. The colour of the fog therefore depends on the light source that illuminates it:
1. **Sunlight:** Natural white sunlight usually shows the fog as grey or white.
2. **Artificial light sources:** Different coloured headlights or lamps can change the colour of the fog. For example, a bright yellow light source can change the colour of the fog to yellow, and a red one to a reddish tint.
3. **Use of colour filters:** Colour filters placed in front of a light source can be used to change the colour of the light emitted, thus influencing the colour of the fog.
It's important to note that fog in its natural state can tend to dull colours, making the original colours paler and less intense.
