"HAPPY HALLOWEEN" 是一张可打印的万圣节涂色页，采用可爱简约的黑白线条风格。一只带弯曲茎的微笑南瓜从长方形牌子后探出头，牌子上是两行堆叠的圆润描边字母，留白等待上色。你可以替换问候语或加入名字，制作自己的涂色页。

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.
