Heddels explains Caste
The caste of a pair of jeans refers to any extra color tones that may be present in the fabric, sometimes added through an additional dyeing process.
For example, “greencast” denim, with a turquoise/greenish tint, is dyed in a green sulfur bath before being dyed with indigo. On the other hand, “redcast” denim, with an almost purplish tint, is denim that has only been dyed with pure indigo.
