What's the difference between a watercolor pen and an oil pastel?

First, the advantages of colored ink pens are rich and bright colors, and the oil pastel has good color overlapping performance, which fully shows the oil painting effect.

1, the oil pastel feels delicate, smooth, spreads well, and has excellent color overlapping and mixing performance. It can fully show the effect of oil painting and meet the needs of various painting skills and difficulties.

2. The pen case of some color ink pens can also be divided into several vertical watercolor grooves, and each groove is filled with different watercolors, so that the color ink pens can write Chinese characters with different colors or draw different patterns at one time, and the colors can be adjusted at will. A pen can write Chinese characters or draw a large area of calligraphy and painting at one time, with rich color changes, which is more suitable for calligraphy and painting creation and improves painting effect.

Second, the colored ink pen is easy to dry, the two colors are not easy to blend together, the drawing paper is easy to penetrate, the oil pastel is too hard and easy to break, and it is easy to dye hands and mix colors.

1, crayons have the disadvantages of short time consumption, uneven moisture, unnatural transition, and disharmony between the two colors, and are generally suitable for drawing children's paintings. Watercolor pens fade easily when exposed to water.

2. The oil pastel will break if used too hard, and it is easy to get on your hands when painting, and the raw materials contain a certain amount of soluble heavy metal elements, such as lead, barium, chromium, antimony, cadmium, mercury and arsenic. Unconsciously ingesting these heavy metal elements will cause some harm to human body.

Thirdly, oil pastels are widely used and are suitable to be used with other painting materials. The combination of watercolor pen and other painting materials has limitations and is more suitable for children.

Oil pastels with other painting materials:

Oil-water separation method (utensils: palette, watercolor, brush) brushes watercolor on the picture drawn by oil pastel, which produces obvious oil-water separation effect. Because oil and wax are the basic materials of oil pastels, watercolor "resists" mixing with them, achieving a unique oil-water separation effect.
