What is the difference between marker pen and watercolor pen? Which is more worthwhile?

Many novice painters can't tell the difference between marker pen and watercolor pen. Although both can be painted, there are still great differences. Today, I will share it with you.
1. Pen head
The heads of marker pens are generally flat (also round and pointed), and the heads of watercolor pens are generally round.
However, different heads of markers have different functions. Fine, brush, and broad are three common types of markers. Fine (thin) is suitable for marking lines. Brush (soft) is flexible and soft. broad (thick) is generous and thick. The classic head of markers can be painted in a large area. The functions of the heads are different, and the matching is more comprehensive.
2. Type
There are two kinds of marker pens: water-based and oil-based, and only one kind of watercolor pen is water-based.
A. There are two kinds of markers: oil-based markers and water-based markers. Oil-based markers are mostly used for one-time quick drawing, which can dry quickly, water and dry. Although not soluble in water, it can be soluble in alcohol. If the pen is dry, add a little alcohol into the refill and then use it for a period of time. The water-based marker is bright and soluble in water. It can be used for a period of time after adding some water to the refill.
B. The watercolor pen includes monochrome watercolor pen, two-color watercolor pen and multi-color watercolor pen. The monochrome watercolor pen only has color difference, including 12 colors, 24 colors, 36 colors and other color numbers. The two-color watercolor pen can be written in two colors. The multi-color watercolor pen is made of multi-color refills together to form a pen head, which is often used in beauty painting.
3. Overlay color
The marker can fold colors and express the desired effect by mixing colors. The watercolor pen cannot fold colors. The marker is easier to color than the watercolor pen.
4. Color number
Generally, watercolor pens are sold in a box of 12, 24 and 36 colors. Generally, when we just started painting when we were young, we used watercolor pens most. Markers can be sold separately. It is also possible to buy only one color. However, there are many colors of markers. If you want your work to be more high-end and draw a gradient effect, you must buy more colors.
5. Price
The price of marker pen is higher than that of watercolor pen.
6. Purpose
The advantages of watercolor pen are sufficient moisture, rich color and bright color, while the disadvantages are uneven moisture, unnatural transition, and two colors are not easy to reconcile together, so it is generally suitable for children's painting; The advantage of marker pen is that the water content is uniform, the color contrast is weak, and the two colors can be well coordinated, which can draw architectural renderings, industrial design renderings, and POP advertisements.
7. Effect
The painting made by watercolor strokes is rough and uneven in color. Because it is water-based, it will break if coated with too much paper, so it cannot be regarded as a professional work. The marker can stack colors and draw gradient effects. And the marker has strokes, which can be used to show highlights, shadows and other effects. More professional.
