Further info will be added to the "lightfast testing and art supply review" section. This includes any other videos I've made about this company, still images of example art, a collection of color charts, along with fugitive fading results. I share my experience on hundreds of pigment and dye ingredients from dozens of painting, drawing and craft supply manufacturers.
If you would like to buy any of the supplies I used in this video, the Amazon links are below. As an Amazon Associate I earn from qualifying purchases. I've also included links to the waterproof inks, pens, brushes and papers I use in all of my reviews. For watercolor, gouache or ink painting, I use small round brushes by Princeton. Heritage series is ideal for a sharp point, small details and snap. Their Neptune series is a synthetic imitation squirrel hair, which is a very soft brush with an amazing ability to hold a lot of water for washes.
*AS OF JAN 2020 THIS SET IS NO LONGER AVAILABLE ON AMAZON* Check Rosa's website for more info at https://rosagroup.com.ua/ Their Ukraine sellers map may offer links to other websites that stock their paints.
Please note that the following link, where I originally purchased the paint on Amazon is no longer active. However, they did offer it worldwide throughout 2019 until the Christmas season. It's possible that this link may be restored after sellers restock after the holidays. Rosa Gallery (title was written as Ronald's Gallery) watercolor https://amzn.to/2X3qcAj
