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.
