A few quiet answers
What is birthday color cafein?
It refers to the popular Japanese idea that each day of the year corresponds to a color — widely known through the original cafein.jp chart and similar sites.
How is my birthday color decided here?
We assign a traditional Japanese color to each of the 366 calendar days (including February 29) with a deterministic map. The same birthday always returns the same color.
How is this different from cafein.jp?
The original cafein.jp table is a hand-curated chart. Ours is an independent rebuild with traditional Japanese color names, bilingual traits, and a garden-inspired reveal experience.
