   STAND BY ME International BAR - 神戸・中山手通
   Evening-green-and-coral theme. VARIANCE 6 / MOTION 3 / DENSITY 3
   Theme lock: dark, whole page. Accent lock: singing coral.
   Radius lock: 10px everywhere.

   WHY THIS PALETTE. Reviews describe a small international bar
   where Japanese and foreign guests end up singing together,
   teaching each other words and trying each other's liquors. So
   the ground is a deep evening green, the colour of a quiet room
   late at night, and the single accent is a warm coral: a voice
   colour rather than a neon one. Distinct from every existing
   dark site: 09-knot is blue-grey slate with CYAN, 05-tamaya is
   night INDIGO with karashi gold, 19-hana is black cherry with
   champagne, and Puentech uses petrol teal as an accent on warm
   paper, the opposite role. No site pairs a green ground with a
   coral accent.

   Contrast, computed from these hex values, not assumed:
   text #eaf2ec on bg 12.44 / muted #a9c0b4 on bg 7.51, on bg-3
   5.89 / accent #f0966b as text on bg 6.41 / ink #2b130a on
   accent 7.73.
