一幅没有文字的圣诞树黑白涂色页，采用粗线条的幼儿线稿风格。粗圆的轮廓勾勒出分层的树形、顶部的五角星、四个带盖的圆形彩球和梯形树干，内部留白供上色。可直接打印给孩子涂色，也可加入自己的标题、姓名或祝福语，并把彩球或星星换成其他图案重新制作。

Create a black-and-white Christmas coloring page for a 3-year-old, portrait 3:4. On a pure white, untextured page, draw one large, friendly Christmas tree centered on the canvas, with a simple five-point star at its tip and only a few large, round ornaments spaced clearly across the branches. Use very thick, smooth, uniform pure-black outlines and closed, generously sized shapes that are easy for small hands to color. Keep all interiors white and open; leave broad white space around the tree and generous safe margins. Make the tree the single clear subject, with a simple, chunky tiered silhouette and no tiny details. No text, no extra Christmas motifs, no color, no gray, no shading, no hatching, no texture, no solid black areas, no border.
