DaVinci's Cadmium Yellow Medium is the shade of yellow you should choose if you are looking for the color of a buttercup flower or a lemon meringue pie, but it can be successfully, smoothly mixed with any other color of DaVinci oils, so you can create the exact color you want, as well as make yourself an even larger palate of colors. You can also mix them with regular linseed oil paints to further make the color your own invention. To make the colors more transparent, you can even thin any of the colors with paint thinner, but be careful not to lose any of the paint's smooth brushing capabilities. DaVinci's oils are made from permanent pigments and are smooth and creamy, so they brush on easily and evenly. DaVinci paints are made with the finest ingredients. The paint making process is subjected to constant scrutiny in the laboratory, insuring you are getting the best paints of the highest quality. You can buy them in 40.6 ml tubes.
