DaVinci’s Thioindigo Violet oil paint is what you are looking for to paint any shade of grape, glass of wine, wood violets or iris, because it can be mixed or thinned to create the exact color you want. Leonardo DaVinci never had it so good when he was painting the Mona Lisa. These oil paints named for him are made from the highest-quality ingredients, creating properties in the paints which makes them consistently creamy and smooth. They brush on to the prepared canvas easily and give you the even coverage you are looking for, yet they can also be thinned for more transparency, or mixed with regular linseed oil based paints for more variety. While these paints are being made, laboratory technicians are in constant attendance to make sure the process goes just right, insuring every batch of paint comes out perfect. You can buy the DaVinci oil in 40.6 ml tubes. Made in The USA.
