Coloring Tips

Use a 3–4 tone palette for the shell geometry: base olive, mid teal, and deep brown for the deepest contour lines.

Color each coral branch differently to separate the labyrinthine reef—try coral pinks, warm orange, and muted teal with light-to-dark gradients.

For the turtle flippers, blend two greens (sage → emerald) and leave thin contour lines darker to keep the motion crisp.

Add an “undersea depth” effect with light circular shading dots near the reef base using a fine marker or colored pencil to follow the contour textures.

Pick 1–2 accent colors for seaweed and fish silhouettes (e.g., seafoam green for seaweed, soft navy for fish) to make the contour-only outlines pop without muddying.
