Can different brands of oil paints be mixed?

Generally speaking, they can be mixed unless otherwise stated.

Oil color is a kind of special paint for oil painting, which is made by mixing and grinding pigment powder with oil and glue.

Most of them are sold in the market in tubes, but you can also make your own.

The basic components of oil paints, like other painting pigments, are composed of pigments, extender pigments, carriers and certain auxiliary materials such as plasticizers, stabilizers, retardants or driers.

The pigment powders used by ancient masters were mostly derived from earth and minerals.

The other part comes from plants or animals.

Today's industrial pigments have eliminated some pigments that are not ideal in terms of compatibility, but there are still some taboos for blending some pigments with each other.

Mixing contraindications Note: 1. Some brands of oil paints have specific text on their packaging indicating the possibility of discoloration when mixed with other colors to remind users to pay attention.

2. Some are represented by marks. For example: Japan's Holbein brand oil paints are marked as follows: 1.

Mixing with lead-containing pigments S and lead-containing pigments 3. Do not mix with sulfur-containing pigments 4. Some oil painting technique books introduce the knowledge of pigment mixing and mixing taboos, which have been practiced by painters and pigment chemistry experts for many years.

Summarized on the basis, it deserves attention.

Although it may actually be difficult to do completely, it pays to know something about it and pay attention to it in your painting practice.

Pigments containing sulfur compounds should not be mixed with each other. Pigments containing lead, iron and copper are taboo with pigments containing lead, iron and copper. 1 Pigments containing sulfur compounds in oil paints such as ultramarine, vermilion, cinnabar and cadmium red

They are all good colors in themselves and can be mixed with organic pigments and zinc and titanium whites, but it is taboo to mix them with pigments containing lead, iron and copper.

2. When sulfur meets lead, iron, and copper, lead sulfide or copper sulfide is produced, which will turn the color black over time.

Lead white pigments are basically no longer produced in China, and there are not many copper-containing pigments. However, synthetic iron oxide pigments and lead-containing chromium pigments are major categories of pigments and should be avoided.

Azo pigments and lake pigments Zinc-titanium series white pigments Azo pigments in organic pigments such as yellow-red series from lemon yellow to purple-red Lake pigments such as blue-violet series from lake blue to rose red, and zinc-titanium series white

Mixing pigments will cause varying degrees of fading, especially red and purple, which must be avoided.

Pink, rose, violet and green lotus products made with lake pigments have serious color bleeding and are best discarded.

Iron oxide series pigments, lead-containing compounds 1. Sulfide-containing pigments Various natural earth mineral pigments and synthetic iron oxide pigments, such as earthy yellow, earthy red, and brown ocher colors are the most important and stable color series among pigments

, can be mixed with most pigments, but will change color and turn black when it encounters sulfur-containing colors.

Therefore, mixing with sulfide-containing pigments such as cadmium red and yellow, ultramarine blue, and red dart should be avoided as much as possible.

2. Pigments containing sulfides. Domestic art pigment manufacturers no longer produce lead white pigments and replace them with non-toxic titanium white or zinc white.

However, various foreign brands of pigments have retained this traditional pigment because lead white has its unique advantages.

3. Lead white, chrome yellow, chrome red and lead chrome green series of pigments.

4. Lead compounds will also turn gray and black after mixing with sulfur-containing pigments, which should be avoided.
