Are white pigments important? How is white pigment made?

First of all, color is something that everyone who studies painting should learn, whether it's an art student. Learning color is naturally inseparable from something called paint. Among them, white is the most important.

The white is divided into zinc white and lead white, zinc white has a higher hiding power, but zinc white is slightly colder and brighter than lead, and lead white is slightly gray and has lower brightness. It can be used according to the picture it draws.

According to statistics, during the training period, an art student needs to use 5 cans of white paint per week. White pigment is so important and commonly used that it is one of the indispensable colors in painting without it. It can be used a little more, a little less, and it can have a devastating effect on the picture.

The main function of white pigments is to enhance the brightness of the color and reduce the purity of the color. When you're painting near highlights, white paint helps to shape the body, making it bright, solid and prominent.

At the same time, pay attention to the coordination with other colors, otherwise the picture will look pale and weak. White pigments are mainly divided into lead white, zinc white and titanium dioxide. Lead white is the most frequently used white pigment in traditional European oil painting, it is very stable, but it is poisonous; Zinc white is non-toxic, but it eats more oil, so its coverage is not very good, it dries slowly, and it is brittle and prone to cracking; Titanium dioxide has strong coverage, dries quickly, and is easy to turn yellow after drying, and is often matched with zinc white!

The combination of zinc dioxide and titanium dioxide not only reduces the brittleness unique to zinc dioxide, but also improves the shortcomings exposed by the use of titanium dioxide alone. It is the most commonly used white pigment in painting nowadays! With so many functions, it's no wonder that white pigment is favored in the art world.

There is a saying that the most precious thing in the world for art students must be white paint. When half of the white paint is dug out, and some classmates and friends borrow white paint from themselves, and then they stain their white paint, this pain is also very painful, if you are an art student who pursues perfectionism, then the result can be imagined.

It is indeed very important, white pigment is not mixed with other pigments, it can only be extracted directly from white objects.

White pigments are really important. White paint is actually colorless, and the reason why it is important is that the colors of students are painted gouache paintings, and one meaning of powder is white, and gouache needs white more than any painting. Generally, if there is one color for each grid in the box, white will inevitably occupy 2.

The white pigment cannot be picked out, because it is a single color, and the raw materials are usually titanium dioxide, zinc white powder, lithopone powder and the like, while the natural Chinese painting pigment is made of clam shells.

White pigment is not very important, there are few places to use, but it is one of the essential pigments, white pigment is a kind of red, orange, yellow, green, cyan, blue, violet.

White pigments are important and need to be used in art. The white pigment is not blended, and it is difficult to clean the white pigment once it is dirty.

It is very important, and it is used in many places, and it is made of lime after treatment.

Because of its special nature, there is no way to make it out with pigments.

The red pigment plus the blue pigment and the red pigment absorb all the light, so it becomes black. As long as it is not white, the pigment will absorb the light of the other color, so according to this theory, white cannot be blended with the pigment.

Pigments can be classified according to the class of compounds they contain: inorganic pigments can be subdivided into oxides, chromates, sulfates, and silicates.

Borate, molybdate, phosphate.

vanadate, ferricyanate, hydroxide, sulfide, metal, etc.; Organic pigments can be divided into azo pigments, phthalocyanine pigments, anthraquinones, indigo, quinacridone, dioxazines and other polycyclic pigments and aryl methanes according to the chemical structure of compounds.

pigments, etc.

Generally, pigments can't jump out of white, white is a mixed color of all colors, but from the nature of pigments, red pigments only reflect red light, and absorb other light, and so on, so red + blue + yellow pigments absorb all light, is black. Any non-white pigment has to absorb a certain color of light, so it cannot be turned white.

Hello, it is a pleasure to serve you. 1: Red + Green + Blue = White, Yellow + Purple + Blue = White, Purple + Green = White, Yellow + Blue = White, Green + Red = White, Red + Green = Yellow, Red + Blue = Purple, Green + Blue = Cyan, This is the principle of three primary colors.

2: Then it depends on what the three primary colors are, the three primary colors of pigments (red, yellow and blue) are not white, the three primary colors of light are red, green and blue, that is, RGB, you can tune out white, mix them together in proportion, it is white, the use of optics, pigments can not be adjusted out of the first of all, any color belongs to the color type, whether black or white is the color, you say pure white can not be tuned, with other color tones can be tuned close to "white" actually belongs to gray in the color of the three primary colors pure white Black can't be blended out, and you don't actually need a solid color when you paint, any kind of item will be affected by the environment, so you should also mix other colors when painting.

Hello dear! Zhikuan is very happy with your question: I have found out that white oak pigments can be prepared by different methods.

Here are some commonly used methods:1TiO₂:

Titanium dioxide is a common white pigment that can be prepared by the processing of titanium ore. This pigment has a wide range of applications in both industry and art. 2.

Bleach: Bleach removes the color of a substance while making it white. This method is commonly used in the production of textiles and paper.

3.Lime powder: Lime powder is a natural white substance that can be prepared by the processing and firing of limestone.

This pigment has applications in architecture, painting, and other fields. 4.Mix other pigments:

White can also be achieved by mixing other pigments. For example, by mixing pigments such as yellow and blue, you can get a light white color. It should be noted that the quality and characteristics of the white pigments obtained are also different due to different pigment preparation methods and formulations.

Therefore, don't touch the white paint of art students, otherwise they will "commit suicide" in minutes, or let you "commit suicide"!

White pigment is very important for art students, because many of the remaining colors in the process of painting are blended through the combination of white pigment and other pigments, so white pigment is an indispensable basic material for art students.

White paint is the only color that has no variegation at all for art students. White pigments enhance color brightness and reduce purity, which is beneficial for the shaping of shapes, and is especially effective for depictions of close-up, solid and high-light. In painting, white pigments are important.

It is important because white pigment is generally used as a base material for painting, used to mix colors, and white pigment is indispensable for art students.

White pigment is very important, white pigment is mainly used to neutralize other colors to adjust the desired color, and the appropriate color can be better expressed.

What color plus what color equals white? ”

To put it simply, the red, green, and blue colors of color light are synthesized into white, as shown in the figure below

That's what the picture is aboveChromaticThree primary colors

And then there's what we often call red, yellow, and blue, and they're all black

See image below: <>

Here it isThe three primary colors of the pigmentSo, in the end, you can't make white with pigments, but you can make white with light.

Other colors in gouache cannot be adjusted to white because white is a base color. White paint can be purchased at the art shop. Most of the gouache pigments are transparent, composed of powdery materials, fixed with glue, and have strong coverage.

Therefore, when painting gouache, I often start with the darkest color. It can be covered layer by layer. If you have the patience, you can also paint the same effect as an oil painting, but the color is darker when the paint is wet, and the color becomes lighter when it dries.

There are also purple colors such as rose red and violet, which are easy to turn out. So it is not used as a base. The gouache pigment is very fine, and the color is very beautiful when it is dissolved in water, but it cannot cover the base color.

Ultramarine, ochre, earth red and other colors of watercolor pigments are mineral pigments, which are prone to precipitation when used alone or mixed with other colors.
