!nb Create an editorial header illustration for an article titled “Oltre Seoul e Busan: la Corea laterale che non entra mai nei programmi”. Visual concept: a simplified map of South Korea drawn with clean, minimal lines. Show a highlighted travel route that avoids the typical tourist stops (Seoul, Jeonju, Gyeongju, Busan) and instead branches to lesser-known places along the east coast, south coast, and inland. Add a few small, subtle icons: a mountain, a ferry/boat, a temple, and a coastal cliff.
Style: modern flat vector / editorial illustration, minimal, lots of negative space. No text on the image.
Color palette: warm off-white background (#F5F1E6), deep green lines (#0F3D2E), with a small gold accent (#C9A227) used only to highlight the “lateral” route.
Constraints: no flags, no photos, no gradients, no 3D, no watermark.
Aspect ratio: 16:9 (Substack header).
