This coloring page features a man wearing a light grey sweater with dark grey stripes for contrast. The V-neck neckline is a classic style that is timeless. I would recommend starting by coloring in the grey stripes; this will emphasize the look of the sweater and add a little more depth. After that, adding some lighter grey shading to the sweater itself gives a more realistic feel. I would also suggest adding a few splashes of color, if desired, such as blues and greens, to create a more interesting look. To finish it off, adding some highlights and shadows with duller gray shades will bring the image to life and make it look complete.
