Has anyone here heard of Viviva Colors? They are a watercolor company out of India and they recently contacted me about trying out their watercolors which come on paper palettes so that they're portable. They are hoping I will like them and write something favorable about them on my blog, and a nice review on their website. I just got the set today but haven't used them yet. I was wondering if anyone else here had been contacted. I think they found me on Insta. I can't really tell if they would be considered professional grade, but I will try them out to mess around with.
