why some pistachio creams are green when the actual pistacho doesn't really look green?

Some pistachio creams appear green due to the addition of food coloring. Although pure pistachio paste, which is made from ground pistachios, tends to have a light brown color with only a slight green hue, suppliers often add chlorophyll to enhance the green color of the product. This practice is driven by consumer expectations, as many associate a bright green color with quality and authenticity, despite it not reflecting the natural color of the nuts^[3].

In fact, pure pistachio paste is not vibrant green, and the final color of the creams can vary greatly based on the method of preparation and the mixture of ingredients used^[6].
