It might surprise you, but 'yellow' kratom does not exist, there are no yellow veined leaves grown on Mitragyna speciosa trees. Typically, yellow kratom is a fermented leaf or a blend of various leaves. Yellow bali in particular is a blend of specially fermented bali leaves (red,white and green) cured to a golden colour. As a result of the process, the alkaloid content is modified therefore is unlike any other bali strain you have tried.
