Style

Colors and fonts to represent the apps and website. The goal is to be clean, legible, but never generic. The palette is built from traditional Japanese colors — woodblock blues, pigment greens, earth-toned accents.

Color · in priority order

1 — Green (primary)

The primary brand color, from the site homepage. Forest is the dark anchor; verdigris is the lighter shade for tints and accents.

Pine #2F453A --pine · 松葉 matsuba Secondary green (web).

Olive #4C5242 --olive Body text and utility green (web).

2 — Blue (secondary)

All the blues come from Japanese woodblock prints, not a generic web-blue: the Prussian blue (ベロ藍, bero-ai) and indigo (藍, ai) Hokusai used in The Great Wave.
