What are colored lead and colored pens?

"Colored lead" (as shown below) refers to a drawing pencil made of colored pigments instead of graphite. This kind of pencil is made of ordinary pencil, that is, pigment and clay binder. There are many brands of colored pencils to choose from, and the supply of colors is also very wide. However, because some brands indicate the ingredients contained in pigments, most of these ingredients are not recognized by painters, so it is generally not recommended to use colored pens for artistic purposes. There are also some special varieties that can be used, such as colored pens made of water-soluble pigments. They are used in the same way as ordinary colored pencils, but the marks they draw can be painted with a wet watercolor pen to produce a rendering effect. Because this pencil contains soluble pigments, it is not suitable for painting durable works.

"Marker" is a special drawing color pen for writing or painting. It contains ink, usually with a pen cover. Generally, the pen tip is hard or soft. The pigment of marker pen is volatile and can be used for quick drawing at one time. It is often used to design articles, advertising slogans, posters or other artistic creations. You can draw thick lines with little change. Box-head pen is a kind of marker pen. At present, marker pens are also divided into water-based and oil-based inks. Water-based ink is similar to colored pen, and contains no oil essence. Oily ink is more irritating and volatile because it contains oil essence. If the paint falls off the toy, you can use a marker to make up the color.
