What do different colored stripes mean?

Stretch marks are still a light pink or reddish color in the early stages.
These stretch marks are still very fresh and is a sign that the skin is in a phase of change.
Whereas white or light gray stretch marks indicate that the skin has relaxed and are the subsequent result of the light pink or reddish stretch marks. Often white stretch marks are a few millimeters wide, or even a few centimeters long.
