Koi Names
Koi carry centuries of Japanese ornamental breeding behind them, and their calm, unhurried movement through a pond suits serene, elegant names far better than anything goofy or hyperactive-sounding. This page starts the generator with the Color picker set to Multicolor and a koi-pond context already prefilled.
Both are just a starting point — adjust the Color picker if your koi leans toward one solid shade, or edit the context box for a more specific pattern like Kohaku or Sanke.

How it works
How we generate names
Written fresh, every batch
Names are generated from what you pick — species, vibe, personality, your notes — not pulled from a fixed list.
No repeats
Each new batch skips every name you've already seen this visit, so “More like these” keeps finding new ones.
