1. Chose your palette.
Using too many colors can create a result that is messy and confusing to the eye. If you want an image that is harmonious, try limiting the number of pencils you use, and mix them to create hues.
This will emulate the way the eye perceives color in the outside world (where everything is bathed in the same light) and ensure that every element of your image tones with the others.
As a fun exercise, you may wish to look at a color wheel and chose two colors which are either opposite, or next to each other on the wheel, and exclusively use these. Try using three colors, then four, then five. Perhaps you'll find a combination of colors that is especially pleasing to you. Perhaps you'll find that you have a preference for some colors and a dislike for others. Enjoy trying many different combinations.
2. Ask yourself where the light is coming from.
In our world, light either comes from the sun or the moon, or from artificial lights. It behaves in a set, and predictable way. To say it in a simpler way: light follows a trajectory. For instance, if it falls down from the right, the shadow will be cast to the left.
Think of yourself as a movie director. You have the control over how/where you want to direct your viewer's eye. So study the way light behaves when it falls over objects. Look at the way shadows appear in nature. Are the edges sharp? Blurry?
Being conscious of the light source you chose to create of this will help you greatly.
3. Don´t rush. Go slow.
Pencil coloring is a slow technique. Depending on your personality, and the time you wish to dedicate to your image, this technique can either seem excruciatingly; or wonderfully slow.
Don't rush. Use a light, circular motion with your wrist and tread lightly.
Be aware that in nature, there is no flat ink. Everything is a mix of many colors. Take a look at the way your cat´s hairs shine under the sunlight. Nothing is as colorful as a black cat.
Children should be taught that pencil colors can be mixed, just like paint. The trick is to gradully add pigments to the area you are coloring.
So if you rush with your pencil strokes, you will not be able to erase, or lighten what you have colored.
Can you tell that I am in love with my pencils?
They've been my friends and my travelling companions all over the world. They weigh little and only ask for a bit of paper, and a sharpener or a knife.
Are you in love with your pencils?
Allow yourself the time to color slowly, meditatively; and you will find that with pencil coloring, you will achieve a result that is wonderfully rich, delicate and rewarding to the eye.
