How to use this prompt

"Thick closed black outlines" is the phrase that produces coloring- book linework rather than a fine illustration; "closed" matters because DALL-E leaves gaps in the outline, and an unclosed wall is uncolourable. Naming the castle parts explicitly (tapering towers, conical roofs, crenellated battlements, arched gate) gives DALL-E the structure it needs rather than a generic castle silhouette. "Stylised clouds and a round sun" keeps the sky simple; detailed clouds distract from the colouring surface. The 4:5 portrait suits a printed colouring page. "Coloring-book ready" is the phrase that gives DALL-E permission to keep the linework bold and simple rather than adding crosshatching detail that ruins the colouring premise.

Variations to try
