The marker is generally divided into oil and water. The pigment of the former can be diluted with toluene and has strong permeability, especially suitable for drawing on tracing paper (sulfuric acid paper); The pigment of the latter is soluble in water, and is usually used for painting on tighter cardboard or coated paper. In the drawing of indoor perspective, oily markers are more commonly used. The technique of oil-based marker is also introduced here.

The water-based marker is bright and transparent in color, but it will turn gray after many times of color superposition, and it is easy to damage the paper surface. Also, if you use a water-stained pen to smear on it, the effect is similar to that of watercolor. Some water-based markers will be water-resistant after drying. So when you buy a marker, you must know the properties of the marker and the way it is painted. This kind of painting tool can be bought in the design supplies store, and can be painted as long as the cover is opened, and all kinds of materials can be colored.
