Hello there, I'm a specialist in automotive fuels and their various characteristics. When it comes to diesel fuel, the color can be a useful indicator of the type and quality of the fuel. Diesel fuel is a hydrocarbon fuel derived from crude oil, and it is typically used in diesel engines. The color of diesel fuel can vary due to several factors, including the source of the crude oil, the refining process, and the additives that are included to improve performance and longevity.
In many countries, diesel fuel is dyed to differentiate it from other types of fuel, such as gasoline. The dyeing process is not only for identification purposes but also to prevent tax evasion and to ensure that the correct fuel is being used in the appropriate engines. Different countries have different regulations on fuel dyeing, and the colors used can vary widely.
Now, regarding the specific historical context you've mentioned, it's important to note that the color coding system for fuels can change over time and is subject to the regulations and practices of the specific era and region. During the time of Communist Party rule, as you've indicated, there was a state-owned monopoly on fuel, and certain color codes were used to differentiate between various grades of leaded gasoline. However, it's crucial to understand that these color codes were specific to that time and place and may not be applicable to diesel fuel or to the present day.
For diesel fuel, the color can range from a light yellow to a dark brown, depending on the refining process and the presence of additives. The brown color you've mentioned was indeed used in some regions to dye diesel fuel, but it's not a universal standard. In modern times, diesel fuel is often dyed to a bright red or green color in many countries to distinguish it from other fuels. The bright colors make it easier to identify the fuel at the pump and help prevent misfueling.
It's also worth mentioning that the quality of diesel fuel is not determined by its color alone. While color can be an indicator of certain characteristics, the most reliable way to assess the quality of diesel fuel is through laboratory testing. This testing evaluates various parameters such as sulfur content, cetane number, and the presence of contaminants, which are critical for the performance and longevity of diesel engines.
In conclusion, while the color of diesel fuel can provide some information about the fuel, it's not a definitive measure of its quality. The dyeing of diesel fuel is a regulatory practice that varies by country and is subject to change over time. For the most accurate assessment of diesel fuel quality, it's best to rely on laboratory testing rather than visual cues alone.

However, during the time of Communist Party rule, the state-owned CPN fuel monopoly dyed leaded gasolines (marketed as "ethilins") in the following colors: 78 - blue, 86 - green, 94 - yellow, 98 - red. Diesel fuel, although unleaded, was also dyed a brown color.
