I'm a specialist in the field of fuel and energy, with extensive knowledge on the subject. Diesel fuel, in its natural state, can vary in color from being colorless to amber. This color variation is due to the presence of various impurities and the composition of the crude oil from which it is derived. The refining process plays a significant role in altering the color of diesel fuel.
When refineries process diesel fuel to reduce the sulfur content, which is a critical step to meet environmental standards and improve fuel quality, the color of the diesel tends to become lighter. This is because the removal of sulfur compounds, which can contribute to a darker hue, results in a cleaner, lighter product. The color change is an indicator of the level of refining and the extent to which impurities have been removed.
Low sulfur diesel fuel, also known as ultra-low sulfur diesel (ULSD), has a sulfur content of no more than 15 parts per million (ppm), as per the regulations set by the U.S. Environmental Protection Agency (EPA). This stringent requirement leads to a more refined product. As a result, when diesel fuel undergoes the necessary processing to reach this low sulfur level, it can exhibit a lighter color.
The color of low sulfur diesel fuel can indeed be light in tone, and it's not uncommon for it to appear green, orange, or even pink. These colors are not typical for unprocessed diesel and are a result of the refining process. It's important to note that the color of diesel fuel does not necessarily correlate with its quality or performance in an engine. The color is more of a byproduct of the refining process and the specific chemical composition of the fuel.
It's also worth mentioning that the color of diesel fuel can be influenced by other factors such as the presence of additives, which are used to improve the fuel's properties, such as lubricity, cetane number, and cold flow characteristics. Additives can sometimes alter the color of the fuel, although this is not the primary factor.
In summary, low sulfur diesel fuel tends to be lighter in color due to the extensive refining process that removes sulfur and other impurities. The specific color—whether it's green, orange, or pink—can be influenced by the refining process and the presence of additives. However, the color itself is not an indicator of the fuel's performance or quality.

The natural color of diesel fuels has traditionally varied from colorless to amber. As refinery processing of the diesel fuel increases to remove sulfur, the color tends to get lighter and the diesel can change color. When it changes color the diesel is typically light in tone and can be green, orange or pink.
