FAQs

Q: What is the difference between the western watercolor and the Chinese painting color?

A: The difference is in the binding glue, source material, and opacity.
Western color is designed to be used on watercolor paper which is none absorbent, and stretched before painting, whereas Chinese watercolor is suitable to paint on rice paper stretched after painting. If you use western watercolor on rice paper, the color will run and bleed when the painting is wet-mounted, but Chinese painting color is made with a more stable binder. Still, if you like to use heavy colors in your sumi or Chinese painting, I'd suggest you to use our silicone paper to dry-mount them.

Traditional Chinese watercolor is made from natural dyes and minerals rather than finer pigment particles in western watercolor. Please do not try to use Chinese painting color on regular watercolor paper especially the mineral colors because they are more opaque, not transparent. They are supposed to be used on the wrong side of rice paper.

Finally, I found western watercolor is very difficult to blend with sumi ink--they tend to be muddy or dirty when mixed and applied on rice paper. Chinese painting colors, on the other hand, are very friendly with sumi ink, which serves as the "bone" of Chinese painting. They could be mingled together to create all kinds of colorful gray tones often seen in Chinese paintings.
