The principle of color changing pencil

The principle of color-changing pencil can be expressed and summarized according to its different types:

1. Insoluble discoloration pencil:

– Principle: Insoluble color-changing pencils are mainly made of high-grade particulate pigments that are professionally selected and have high adsorption color rendering. These pigments can be evenly colored and smoothly depicted when used on various types of paper, and the pen refill is not easy to fall off from the core slot.

– Classification: Insoluble color-changing pencils can be divided into dry and oily. Most of the color-changing pencils on the market are of this type, cheap, and the best choice for getting started in painting.

– Features: The effect of painting is light, simple and clear, most of them can be erased by eraser, with translucent features, which can be superimposed by colors to present different picture effects.

2. Water-soluble color-changing pencils (water-colored pencils) :

– Principle: The lead of water-soluble color-changing pencils can be dissolved in water. Before dipping in water, the effect is similar to that of insoluble colored pencils. But when dipped in water, the colors will blur out, achieving a transparent effect like watercolor.

– Features: The color is very bright and bright, and the color is soft. This pencil has two functions, it can be used either as a regular color pencil or as a watercolor brush.

3. Special color-changing pencils (such as Chameleon Pens) :

– Principle: This kind of color-changing pencil actually contains two parts: color-changing pen and pigment cover. The pen tip absorbs, stores, and sequentially drains colors as you draw. If you need to mix another color, just insert another pigment filler and wait a few seconds to achieve the color change.

– Features: A pen can contain a variety of colors, by changing the pigment filler, can achieve a variety of color combination and change.

Sum up:

The principle of color-changing pencils is mainly based on the type and characteristics of pigments used. Insoluble color-changing pencils take advantage of the properties of advanced fine particle pigments to achieve uniform coloring and smooth painting. Water-soluble color-changing pencils achieve watercolor-like effects by dissolving the lead in water; Special color-changing pencils achieve color changes and combinations by absorbing and storing different colors on the tip. These principles make the color-changing pencil more possible and expressive in the drawing and creative process.
