"HAPPY HALLOWEEN" はハロウィン向けの印刷できる塗り絵で、かわいくシンプルな白黒の線画です。カーブしたヘタのあるにっこりかぼちゃが長方形の看板の上からのぞき、看板には縁取りだけの丸い文字が二段に並び、色を塗れます。あいさつ文や名前を入れ替えて、オリジナルの塗り絵が作れます。

Create a print-ready 3:4 portrait Halloween coloring page for a classroom of six-year-olds. Use only pure black, clean, even-weight outlines on a pure white background. Show one large, smiling jack-o'-lantern centered on the page, with a simple curved stem, two friendly oval eyes, and a wide, open smile with a few large, clearly separated teeth. The pumpkin holds a broad, simple rectangular sign across its lower front. On the sign, render the exact words “HAPPY HALLOWEEN” in large, uppercase, hollow outline letters: thick rounded strokes, generous spacing, open counters, and no fill so children can color inside each letter. Keep every pumpkin, face, hand, sign, and letter shape closed and easy to color. Use bold, smooth contours and very few large internal details; no tiny patterns, textures, shading, hatching, gray, color, or solid black areas. Leave generous white space around the main subject, with all artwork inside a clear print-safe margin. No extra text, characters, or background scenery. Flat black line art, crisp edges, suitable for home or school printing.
