Just as some undesirable side effects can occur unexpectedly when taking multiple drugs at the same time, the mixing of various ingredients of pigments can also cause some bad reactions. Some of the pigments will fade or darken when mixed with each other. Although the change caused by the taboo of the pigment composition may not be obvious in a short period of time, it will bring unpleasant results after a long time, and even produce a devastating ending.</p><p><br></p><p>Pigments that should not be mixed with each other</p><p>1. Sulfur compound pigments and lead, iron and copper-containing pigment series</p><p>The pigments containing sulfur compounds in oil paints, such as ultramarine, red dart, silver vermilion and cadmium red, are all good colors by themselves. They can be mixed with organic pigments and zinc and titanium whites, but they should not be mixed with lead, iron, and Blending of copper pigment series. Sulfur meets lead, iron, and copper to produce lead sulfide or copper sulfide, which will turn the color black over time. Lead-white pigments are basically not produced in China, and there are not many copper-containing pigments. However, synthetic iron oxide pigments and lead-containing chromium pigments are the main types of pigments and should be avoided.</p><p><br></p><p>2. Azo pigments and lake pigments and zinc-titanium series white pigments</p><p>Azo pigments in organic pigments, such as the yellow-red series from lemon yellow to purple, and lake pigments such as the blue-violet series from lake blue to rose red, mixed with zinc-titanium series white pigments will cause different degrees of fading, especially Red-purple is more serious and must be avoided. The bleeding of pink, rose, violet and green lotus made with lake pigments is serious and it is best to discard them.</p><p><br></p><p>3. Iron oxide series pigments and sulfide-containing pigments</p><p>All kinds of natural earthy mineral pigments and synthetic iron oxide pigments such as earth yellow, earth red, and brown ocher are the most important and stable color series among the pigments, which can be mixed with most pigments, but only meet with sulfur-containing colors Will change color and darken. Therefore, it is necessary to avoid mixing with cadmium red and yellow pigments, ultramarine blue, and sulphide-containing pigments.</p><p><br></p><p>4. Pigments containing lead compounds and pigments containing sulfides</p><p>The current domestic art paint manufacturers no longer produce lead white pigments and replace them with non-toxic titanium white or zinc white. However, all foreign brands of pigments retain this traditional pigment because lead white has its unique advantages . In addition to lead white, there are series of pigments such as chrome yellow, chrome red and lead chrome green that contain lead compounds. Lead compounds and sulfur-containing pigments will also turn gray and black when mixed, and should be avoided.</p><p><br></p>
