Thank you, Linda, for your comment.
I've worked on a couple more Chinese landscapes this morning.
I found that Marie's Chinese watercolor is very weak compared to the Japanese Yasumoto pan watercolor for brush painting.
And the Chinese ink stick colors that I grind is even lighter by comparison.
And by comparison, some may say that the Japanese watercolor on the far right is more garish but I like those colors even more.
I'm going to try a bit more of the Marie's watercolor before I write it off. There is definitely wastage in using tube paints especially these formulated for the Chinese brush painting. Once dried, you can't reconstitute it without it being crumbly and granular. I don't also care much for Marie's consistency. It's a bit uneven as I see it. It's nowhere close to Holbein gouache. Those Japanese really has a superb formula. Yasumoto pan watercolor is absolutely smooth. Incredibly well made. It's really worth the money. I need to check on Shinhan Korean watercolors.
