Experiment with a variety of different coloring techniques. Blending, shading, dots. Or cross-hatched lines for a new twist. Don’t feel obligated to fill the space with solid color.
Test out colors beforehand so you know exactly what shade you are working with. Grab a separate piece of paper and perfect the correct shade. Find three colors that work well together, and make your own swatches for future reference.
Colored pencils with "soft cores" tend to be more forgiving, letting you add bold color gradually by applying varying amounts of pressure. They offer rich pigments so your colors are more vivid on paper.
Color from the outside and work your way in to stay inside the lines. Read about color theory. Use complementary colors.
Think outside the box!
