Step 20: Go over the final sketch lines with a pen, marker or any other type of permanent ink. Take your time and be careful when you ink to avoid any accidents. After inking, get rid of every pencil mark with an eraser for a cleaner drawing of a horse.
Final Step: Color your horse drawing! Use dark brown for the mane, tail and to create shadows. Color lightly at first and gradually build up to the level of darkness that you like. Pick the direction of the light source so that the shadows are consistent with it. Use dark brown to emphasize the muscles on the horse's legs, neck and body. It's a good idea to use reference as you color for a more accurate depiction of the muscles.
This horse will be brown, so start to add brown lightly throughout the body. Leave a few areas on the neck and body blank for the shine on the coat. Use brown on top of the areas with dark brown too, slowly blending the two colors. Lightly add a bit of black to the horse's mane, tail, eyes and shadows. Vary the pressure on your color pencil to get lighter or darker shades of the same color.
Continue to slowly add different shades of brown and gradually blend the colors together. As you slowly blend the colors, add some light brown and yellow to the blank areas for a shiny coat. Push down harder on your pencil, using light brown and yellow to blend the colors together.
It's a good idea to test your colors on a separate piece of paper before adding them to your horse drawing. Colors are hard to erase, so by testing them separately first, you can determine whether you like them or not. Use a bit of gray at the bottom for the hooves and for shadows on the white parts of the legs.
Coloring like this can be very time-consuming, so be patient and take breaks. For a simpler drawing, just use one color for the whole body and omit the shadows and sheen. You can also give your horse a different pattern. Some horses have big color patches and even spots! If you own a horse, try to duplicate its coat on your drawing.
Using brown and gray, add a cast shadow underneath to ground the horse so it doesn't appear to be floating. Don't forget to pause the video to draw at your own pace.
