Hypancistrus-zebra,
My guess's for your koi would be...
1. Nidan Kohaku - Koi with red on white are generally referred to as Kohaku. It seems yours has two small patches of red so a two step red on white is referred to as a Nidan Kohaku.
2. Kahaku - The koi is clearly red on white but I don't think it follows any specific color pattern.
3. Aka Bekko or Hi Utsuri - Aka Bekko is black on red while Hi Utsuri is Red on Black. I am not a Koi expert so it is always difficult for me to tell which is which when they name color patterns this way. If I had to pick one I would pick Aka Bekko (black on red) because it looks like hints of red show through some of the black markings which would indicate that red is the background color.
Happy Thanksgiving.
