What's the difference between water solubility and oiliness of colored brushes?

Color brushes are divided into insoluble color brushes (oily and dry) and water-soluble color brushes.

The difference between water solubility and oiliness of colored brushes;

1, classification difference:

An oily drawing pen is a colored pencil that is insoluble in water (the other is dry), that is, it is insoluble in water.

Water-soluble colored pencils are pencils made of water-soluble carbon matrix refills, that is, colored pencils that can be dissolved in water.

2. Price difference:

Common colored pencils on the market are generally insoluble colored pencils, which are relatively cheap. Please distinguish carefully when buying.

Water-soluble colored pencils are more expensive than insoluble colored pencils because they contain soluble pigments.

3, the use effect:

Oily painting strokes are light in color and have a translucent effect. Most of them can be erased with an eraser, which is suitable for repeated modification. However, the brush lines are simple and clear, and different picture effects can be achieved through color matching and overlapping.

Water-soluble color pen, its refill can be dissolved in water, and the color will smudge in water, which can achieve the effect similar to watercolor pen. The color is bright and soft. If it doesn't touch water, it has the same effect as an insoluble colored pencil.
