The very reason that an increasing number of hobbyists breed koi is the variety of colors they are available in. Thanks to Japanese breeders, koi fish color has evolved over the years with an amazing array of color patterns and scaling. Different varieties have been categorized and given specific names according to color patterns.
Kohaku is a common variety of white koi with red or orange markings on the back. This variety belongs to the Gosanke category. Kohaku means 'red and white' in Japanese, which is where the fish gets its name. Kohaku hi is a white koi that has wide, red markings on its body. Where the red marking is a single pattern it is known as a straight hi. Black koi with red and white markings on its body are known as Showa Sanshoku.
There are plenty of koi colors for hobbyists to choose from. Yellow, white, black, blue, orange, and dark green are popular varieties. Constant crossbreeding has resulted in many koi fish colors and varieties being developed. The butterfly kio and ghost koi are some of the recent varieties, although they are not considered as pure koi at a competitive level.
