1. Hard colored pencils and soft colored pencils

The lead of a colored pencil is made of a waxy agent (medium) fixed into the shape of the lead by a dye containing pigments. The more the medium, the harder the lead. Drawing with hard color pencils, even if the lead is long, sharpened is not easy to break; Soft pencils risk breaking the core if sharpened too long.

2. Light and dark colored pencils

Light colors are harder, dark or bright colors are softer, all because of the content of the medium in the pen. Try pink, which is close to white. You can immediately see that it is much harder than the bright pink pencil.

3. Paint materials other than colored pencils

Water-soluble colored pencils can be dipped in water and dissolved like watercolors; Because of the small amount of media in the powder wax pen, the drawing will be powdered. After drawing, rubbing with your fingers will erase the powder on the painting, but it is the most suitable for the painting method of smudging. The key pen is a paper-wrapped pencil with a sticky lead, plastic, glass, wood, stone... You can draw anything.

4. The cutting method of the pen lead is a very important factor in drawing

Compared with watercolor or oil color, colored pencils are very limited by material and color mixing changes. Therefore, the strokes of colored pencils become the most important conditions for manufacturing materials. The sharpening method of the pen core affects the stroke, so the choice of the brush is very important. Although the pencil sharpener can sharpen quickly and well, the lines drawn are too uniform and lack of variation. Use a knife to cut, concave and convex nib can draw flavored lines, with the change of Angle, rotation, maybe will draw their own unexpected lines.
