What color is Salmonella typhi?

Salmonella typhi is a bacterium, and as such, it does not have a color. Bacteria themselves are too small to be seen with the naked eye. When grown on culture media, different species of bacteria may have different colors, but this depends on the type of media used and the specific characteristics of the bacteria. Salmonella typhi, specifically, does not produce any particular pigment that would give it a specific color.
