Tideline

Deep indigo wet-paper ground with three humid jewel-tone highlighter accents — a glowing cyan tideline, a hot coral backrun, an amber pool. Dark, luminous, never muddy.

Do
  • · Keep the deep indigo ground primary; use the three accents like highlighters.
  • · Reserve cyan for the lit, active, primary edge and coral for warnings and attention.
  • · Layer washes as transparent glazes so colour stays humid and bright.
Don't
  • · Flood surfaces with accent or let warm coral become everyday decoration.
  • · Switch to a white or pastel ground.
  • · Grey the accents down — bright jewel-tone on dark is the point.
