Coloring Tips and Techniques. First of all _ choose what coloring material you would like to use. There are lots of coloring materials to choose from like: crayons, colored pencils, markers, soft and oil pastels, and many more. It's your choice which media you'll be comfortable in.
Some colors are more transparent than others. Some colors are very opaque. Test your colors on a separate piece of paper to see how they work together. Too many layers of crayon can make the colors resist each other. This can make it harder to add more color. Use as few colors as possible to get your end result. Scratch out small lines and details (such as hair, the veins in leaves and flowers, etc.) with a craft knife. Crayon is excellent for scratching due to the wax. Do not get frustrated! You will need practice to get the look you want. It's worth it!
