I obtained these 'Cotman Water Colors', from Winsor & Newton, for my first attempt at water coloring and although I'm unable to provide any comparisons I am pleased with the assortment of colors, and the price. I've found the colors blended easily and cover nicely, as well; Two of my grandchildren, ages 4 and 7, were very happy to join me and they were amazed with the results obtained by mixing the colors and diluting with water. We really did have an excellent beginning.
