What types can creative line drawing be divided into according to color and form?

The types of drawing lines are points (big points and small points), lines (extension of points), surfaces (aggregation of points and thickening of lines) and straight lines, oblique lines, spirals, curves and combinations of points, lines and surfaces.

Line drawing can also be called sketch. It describes the object you see with a line. It is a kind of painting form that can not only depict the details of objects, but also simply treat them artistically. Line drawing shows different artistic effects because of different tools used. For a long time, line drawing teaching in senior high school has some limitations in form, tools and materials.

In fact, lines can be monochrome or multicolor, and lines of other colors can be added between or above lines to produce rich color changes. You can also draw thick or thin lines with art pens or signature pens, which is in sharp contrast with thick lines drawn with soft pens such as writing brushes.
