[Manufacturer of colored compound fertilizers: Yingcheng Fubang Technology Co., Ltd. Phone numbers: 0712 3228988 and 3232288.

For compound fertilizers, the colors commonly used are those inherent to the fertilizer itself – for example, 15-15-15 potassium chloride-based fertilizers turn red, while those based on potassium sulfate become white. If humic acid is added, the color is usually grayish-black; if this gray color isn’t satisfactory, coloring can be applied to make it much darker. Green and yellow colors haven’t been seen used by any manufacturers in Jilin, while some people use brown colors, but there are drawbacks to this approach. For now, it can only be used in fertilizers with low nutrient content that do not contain urea.] That’s all I know; I hope it’s of some help to you.
