Are these statements true or false?

Indigo: More than just a Spice

Indigo is a color that is traditionally regarded as a shade of blue. It is derived from the plant Indigofera tinctoria and was historically used as a dye in textiles. However, there seems to be some confusion about the use of indigo as a spice. Let's clarify some misconceptions.

Origin of Indigo

Indigo is not a spice that sweetens drinks. Instead, it is a natural dye that has been used for centuries in various cultures around the world. The deep blue color of indigo is highly valued, especially in the production of textiles.

Indigo and Spanish Culture

The statement claiming that the Spanish used indigo in their tea and coffee is false. While the Spanish were known for their influence in bringing various spices and goods to Europe from different parts of the world, indigo was primarily used in dyeing fabrics rather than in culinary practices.
