Diesel can appear in different colors based on its type and the additives it contains. Standard diesel for vehicles is generally a clear to yellowish color. However, off-road diesel, which is not intended for vehicles used on public roads and is tax-exempt, is often dyed red. There is no widely used green diesel in terms of color; when diesel appears green, it could be due to specific additives used by some manufacturers for identification or performance purposes.
