How To Draw Caillou | Kids Coloring Video. Timelapse of drawing Caillou with a blue and green hat, yellow and red t-shirt, peach colored face, pink/purple mouth and white and black eyes . Coloring videos done with Crayola markers or other markers. This drawing video has exciting childrens music you can listen to in the background. Drawing with crayons and colored pencils is also fun. We drew this picture of Caillou with markers because the colors show up very well on white paper, compared with crayons and colored pencils. Fan art of the childrens charer Caillou in PBS Kids.
