* Turgidity is about water pressure, not pigments: Turgor pressure is the pressure exerted by the contents of a cell against its cell wall. This is primarily due to the movement of water into the cell, making it plump and rigid.

* Red pigments are related to other factors: Red pigments, like anthocyanins, are produced by plants for various reasons, including:

* Protection from UV radiation

* Attracting pollinators

* Signaling stress or damage

* As antioxidants

There's no direct link between turgidity and red pigment production. The presence of red pigments is a separate trait determined by the plant's genetics and its environmental conditions.

Example: A plant with leaves containing red pigments can be turgid or flaccid. Similarly, a plant with green leaves (lacking red pigments) can be turgid or flaccid.

It's important to avoid confusing different cellular processes.
