MacConkey agar is yellow (due to the lactose in the agar). When an organism consumes the lactose, the agar turns purple. Purple indicates a positive test.
If the organism doesn't use the agar, the agar stays yellow.
In MacConkey agar, lactose fermentation is indicated by the color change of the colonies. The medium contains lactose as a fermentable carbohydrate and a pH indicator, typically neutral red. When lactose is fermented by certain bacteria, it produces acid, lowering the pH and resulting in a color change to pink or red. Non-fermenters will remain colorless or pale, allowing differentiation between lactose fermenters and non-fermenters.
It's pink, since it can use lactose as it's nutrition source
