The soil on Prince Edward Island is generally a rich, red-brown color. This is due to the high iron content in the soil, which is a result of the island's unique geological history.

Here's a bit more detail:

* Red Soil Formation: The red color comes from the iron oxides in the soil, which form when iron reacts with oxygen and water.

* Glacial Origins: Prince Edward Island's soil was formed by glaciers, which deposited a mixture of sand, silt, and clay.

* Fertile Land: The red soil on PEI is known for its fertility and is excellent for growing potatoes, which are a major agricultural product of the island.

So, while the specific shade of red can vary depending on location and soil composition, the overall color of soil on Prince Edward Island is a rich red-brown.
