Line art, black and white, coloring page by numbers for adults and kids. A4 vertical format (210x297mm). White background, clean thick black outlines, no shading, no grayscale. The main character is a cute anthropomorphic race car resembling Lightning McQueen from the movie Cars — but stylized as a "paint by numbers" template. The car is depicted in a dynamic pose on an empty race track, with large numbered zones inside its body (numbers: 1, 2, 3, 4, 5, 6, 7, 8). The background is minimal: part of a speedway track and a simple checkered flag line. Strict margins: 1.5 cm empty white border on all sides. At the bottom of the image, outside the main drawing but inside the A4 frame, there is a color-number legend box: rectangular, divided into small squares, each square contains a number (1 to 8) and a tiny black-and-white swatch (labeled with color names in English: Red, Yellow, Blue, Black, White, Silver, Orange, Green). No colors filled inside the main drawing — only line art. Very detailed, precise zones for painting by numbers, clean segmentation. Vector-like style. No text inside the main car area except zone numbers. --ar 210:297
