Sudan dye is lipid -soluble dye, thus, it will turn any lipids to red. It mixes with it.
The sudan dye is a lipid itself, therefore you have a lipid layer interacting with another lipid.
If no lipids are present, the red dye will sink to the bottom of the test tube. Sudan (iv) is not soluble in water but soluble in lipid.
The dye stains the bacteria, thus giving them color. Before they were stained they were colorless. It's very hard to see the details of something clear but when colored it's easier.

Usually water is the best control substance for the Sudan IV test.
Dyed as in stained with a dye
Sudan IV is a diazo dye for staining lipids, lipoproteins, and triglycerides. It is used in Sudan staining, wherein it attaches to the fats chemically.
There are many types of dyes available depending on what kind of cells are being stained. Plane cells can be stained with Iodine Bacteria can be stained with Gram's reagent Animal cells can be stained with Trypan Blue. They can also be stained with Hematoxilin and Eosin
The cytoplasm can be stained a pink color by the dye eosin.
Because leukocytes are clear and colorless, they must be stained with an appropriate dye before a differential count is performed
Color remover won't level out the color enough to dye over. Dyeing them black is the only realistic option.
