Beyond the end of the fin. The doitsu scales are dark blue. Red will appear as a lateral line at the base, the red will appear on the cheeks, the abdomen, the base of the fins. In the case of the Hi Shusui the red will appear beside the dorsal ridge. The colour of all other skin should be white or blue.
The word Shusui is generally translated as Autumn Sky.
