If streaking for isolated colonies was done with Serratia Marcescens what is the difference between pigmentation between cells grown at 25 and 37 degrees celsius?

Serratia marcescens incubated at 37 degrees Celsius will have almost a clear pigmentation. However, when S. marcescens is incubated at 25 degrees Celsius it will produce a very distinct red color.
