Question 1

What is birthday color cafein?

Accepted Answer

Birthday color cafein is how searchers usually refer to the Japanese birthday color tradition hosted at cafein.jp — a 366-entry chart that maps each day of the year to a single color. The phrase is also written birthday colour, birthday colour cafein, birth color, or misspelled birthday color caffeine.

Question 2

How is my birthday color decided here?

Accepted Answer

We use two things: the season your birthday falls in (defined by the solar terms of the Chinese calendar), and a deterministic algorithm that distributes 16 colors across each season. The same birthday always returns the same color.

Question 3

Are these real traditional Chinese colors?

Accepted Answer

Yes. All 64 colors are documented traditional hues — drawn from silk dyes, mineral pigments, porcelain glazes, and the vocabulary of classical poetry. Names and hex values are grounded in public-domain sources.

Question 4

How is this different from birthday color cafein jp?

Accepted Answer

The original birthday color cafein jp site is a hand-curated 366-entry table of mostly Western color names — Cobalt Blue, Burgundy, and the like. Ours is algorithmic, built from Chinese traditional colors, and structured around the Chinese seasonal system — a completely different cultural tradition.

Question 5

Can two people share the same birthday color?

Accepted Answer

Yes. With 16 colors per season and approximately 92 days per season, many birthdays share a color. People who share a color often share a season as well.

Question 6

Is my birthday color a lucky color?

Accepted Answer

Not in any mystical sense. Think of your birth color more as a self-portrait: a color that represents the feeling of your birthday, one you can wear, decorate with, or simply keep as a quiet reminder.

Question 7

Can I use these colors in my own design work?

Accepted Answer

Absolutely. The colors themselves are part of a shared cultural heritage — public domain. You are welcome to copy any hex value and use it in your projects, no attribution required.

Question 8

Is there a deeper meaning to the traditional Chinese color system?

Accepted Answer

Yes — traditional Chinese color thought is tied to the Five Elements, the seasons, the solar terms, and centuries of poetic practice. The birthday colors here are entry points into a much richer cultural tradition worth exploring.
