If you are talking about a Gram Stain, then red. E. coli is Gram negative which means that Safranin will stain it red during a gram stain.
Methylene blue can be used to stain E. coli so you can look at it under a microscope. As an alternative, you could try gram staining.
Red.
After 48 hours incubation with e coli, the TSI media will be in black in color.
E. coli is actually green on tryptic soy agar. The agar itself is a white, amber color.

Colony shape and color
Yes, E. coli are Gram negative.
Escherichia coli
Escherichia coli (E. coli) is a rod-shaped, Gram-negative bacterium typically measuring about 1 to 2 micrometers in length and 0.5 micrometers in diameter. It has a smooth cell surface and is characterized by its flagella, which allow for motility. E. coli is generally non-sporulating and possesses a polysaccharide capsule in some strains, contributing to its virulence. Under a microscope, it appears as a pale pink color when stained with Gram stain due to its thin peptidoglycan layer.
e coli
Not. E Coli is a bacterium.
The full scientific name for E. coli is Escherichia coli.
