Kokesuki

Lighter scale. Refers to a scale in a Hi plate or Sumi patch. This term describes scales that are not saturated with colour so that the background shows through. The scale appears thinner than the surrounding area and looks transparent. The colour appears scattered and lack uniformity. This is considered a fault. If the Koi has good deep red it might recover. But in general it is difficult for Kokesuki to fill in. Kokesuki refers to scales that fade or lose colour and result in Hi Mura (inconsistent colour).
