I just wandered over to Winsor & Newton’s website and found a wealth of information about their watercolours, which I have been using and loving for years. Â Here’s the site link: Â http://www.winsornewton.com/resource-centre
So, now when you have questions about the various colors available and properties as well as chemical make-up of types of color you will know how to get wonderful info quickly and easily. Â Enjoy!
