An organism grown in a high nutrient liquid broth to high turbidity always appears to produce a blue pigment and even when a large inoculum is transferred to a nutrient rich agar plate it appears blue. When the researcher noticed it never appears blue when very small colonies were grown in low nutrient agar plates. What is the most plausible conclusion?
