is the term applied to a metallic koi of single color.
The term 'hikari' translates to 'metallic.' Examples of
hikarimuji koi are the platinum ogon or purachina, the
yamabuki ogon (light yellow), and the orenji ogon (orange).
The color of a hikarimuji must be unblemished, uniform, dense,
and shiny. Luster of the skin is an important consideration
for this koi type.
the absence of patterns on a hikarimuji koi, one simply has to
ensure that the head is very clear, i.e., unblemished by black
spots and other imperfections. The body, on the other hand,
must be of uniform color and also unblemished. As mentioned
earlier, luster of the scales and fins (especially the
pectoral fins) is important.
