Vein color refers to the color of the central vein and stem of the kratom leaf at harvest, traditionally divided into red, green, and white. Vendors use it as the primary way to categorize a product’s expected character.
Color is influenced by leaf maturity and post-harvest drying rather than being a fixed genetic trait, and “yellow” or “gold” usually denote a specific drying or blending process. See the Kratom Strains Guide and Green vs Red: A Practical Comparison.
