What color the dyes in the cell sap and in the plastids can color various parts of the plants.

The color of a plant cell depends on the presence of pigments (dyes) in the plastids or in the cytoplasm.
The main plastids that give plants their green color are called chloroplasts and contain the green pigment chlorophyll.
Red, yellow, orange color is given to the cells by pigments that are contained in chromoplasts, and where there is no staining, leukoplasts.
Blue, light blue, burgundy color is given by cytoplasmic pigments.
For example: chromoplasts give the color of the root vegetable of carrots, and pigments of the cytoplasm to the root vegetable of beet.
