Color paste coloring essentials and skills

Keys and techniques of color paste coloring

The following text will mainly talk about the essentials of color matching of hedging colors (complementary colors)!

If the chromaticity is different when toning, the unwanted color should be removed, so when the three primary colors are used, the counter color must be applied.

What is color matching? It is to remove the unwanted color and make the target color more gorgeous. Hedge color is divided into single-color hedge and color-changing hedge.

A single color hedge (main color hedge)

For example: purple neutralizes yellow, blue neutralizes orange, green neutralizes red, (refer to the color table 180-degree straight line color is a hedge color)

Second, color-changing hedging,

Mainly, a main color plus a secondary color will produce a secondary color. This method can remove the variegated color. The difference between single-color hedging and double-color hedging: it is not enough to use purple for orange-yellow, because orange-yellow is a double-color, and blue-violet must be used for coloring. If you use single-color hedging, you can only neutralize one one color, and the remaining colors will also affect the target color. If the color is uneven when hedging, the main reason is that the color is deepened due to the addition of more hedging colors. (I don’t understand this paragraph, please refer to the above hue chart, “orange yellow” – “blue purple” is the color opposite to each other in a 180-degree straight line, these two colors are opposite colors or called complementary colors)

When we are learning to drive, the coach will let us practice reversing the warehouse first. In addition to reversing the warehouse, what we must master is to fine-tune the direction, slowly correct the direction during the driving process, and finally reversing the car. library. And our grading is also a fine-tuning. For those of us who don’t know how to color grading, we can add a few colors based on our feelings, but after adjusting the wrong color, we don’t know how to correct it. Adding colors indiscriminately, the final color deviates farther and farther. After throwing it away, you have to try the color again. This is why many people can’t adjust the ointment with 5 colors. They have always been in a state of vague understanding. They only adjust some simple light colors and colors with less color mixing. . Let’s talk about Tianzhu blue below, the method of fine-tuning the color, I hope it will be useful to you.

The key to coloring whether it is ointment or leather color paste is as follows:

1. When the blue is added more, it becomes bluer?

You can use (yellow + red) to match ===orange yellow

Add a small amount of orange to the prepared color paste to neutralize some of the blue.

2. When the color is dark?

Add a little bit of white to make the color whiter.

3. When more yellow is added, it turns yellowish?

You can use (blue + red) to match === fuchsia

Add a small amount of purple to the adjusted color paste to neutralize some of the yellow

4. When the red is added too much, it becomes reddish?

Available (blue+yellow)==green

Add a small amount of green to the prepared color paste to neutralize some of the red.

Above Tianzhu blue, why do you always emphasize adding a small amount, because adding too much complementary color will only make the color gray, so we are talking about fine-tuning. You usually look at the color matching table, the ratio of the five colors of red, yellow, black, white and blue to each other, first call out similar colors in the general direction, and then make fine adjustments to call out more accurate colors.

The following color chart mainly depends on the RGB parameters

(R=red, G=yellow, B=blue)

Correct blending method of latex paint color

Architectural paint color matching is an important part of paint production technology, and color matching technology requires rich experience. How to prepare the paint color of the specified color card in a short period of time can be said to be a highly technical job. Color matching technology is an indispensable and important process for the production of color paints other than white paints. It directly affects the color of paints. Quality of production, sales and construction performance.

1. The three elements of color

The hue, lightness, and chroma of a color are standard scales for analyzing color.

1.1 Hue refers to the appearance of different colors. The most basic representative colors of hue are five kinds, namely red, yellow, blue, green and purple. The psychological reflection of hue is characterized by warm or cool colors.

1.2 Lightness is the degree of lightness and darkness of each hue perceived by the eye. Different lightness produces differentThe emotional effect of ��, high lightness will give people a pleasant and high-quality feeling, while low lightness will give people a simple, rich, and low feeling.

1.3 Saturation refers to the vividness of each color, that is, the purity and saturation.

2. Color matching

When toning, the two primary colors form a secondary color (secondary color) and the corresponding other color is the complementary color. Adding a complementary color to a secondary color (secondary color) will darken the color and even turn it into gray or black. See Table 2 for the relationship between toning and its complementary colors.

Classification of color tones

The relationship between color palette and its complementary color

Note: There are almost no three primary colors in the colorants used in the market, and most of them are secondary colors. Example: Yellow is reddish and greenish.

3. Commonly used pigments for color matching and their effects

Pigment is a kind of fine powder colored substance, which is insoluble in water or oil medium, but can be uniformly dispersed in the medium and applied to the surface of the object to form a colored layer to present a certain color. Coloring pigments can be divided into inorganic pigments and organic pigments.

When choosing a color palette, pay attention to the following points:

1. When the exterior wall paint is toned, the exterior wall color must be used.

2. The color produced by dual tone fades faster than the color produced by single tone.

3. Bright colors fade faster than dull colors.

4. Try to use inorganic pigments and less organic pigments.

5. Chrome yellow turns orange red when it meets alkali, and turns black when it meets hydrogen sulfide.

Color matching method for latex paint

The latex paint is mainly white and light-colored, and the amount of dark paint is relatively small, and most of them are used on special parts. Therefore, the general architectural paint production plants mostly produce white paints and paints of various colors with colorants.

After the white paint is prepared, the paint of the required color tone is prepared by adding a small amount of the required color paste. The color paste can be prepared by yourself or purchased, but it should be noted that it can be used only when it reaches a certain fineness, at least the same as the fineness of the white paste, because it is directly prepared without over-grinding after adding the color paste finished product. The tone of the final product is generally recolored, that is, at least two or more color pastes must be added, so it is very important to correctly grasp the color matching operation.

(1) When toning, it should be carefully adjusted according to the principle of finding the depth first and then the color. Do not add the dark color paste at one time, but leave a small part and add it as you adjust to avoid excess.

(2) The color paste should be added slowly while stirring. After each color paste is added, it should be fully stirred evenly, and samples should be taken at any time to compare with the sample. But it should be emphasized that half of the composition of latex paint is water, and there is a large color difference between the dry film and the wet film. Generally, the dry film is lighter in color than the wet film. Therefore, when comparing colors, the wet sample should be compared with the wet sample, and the dry sample should be compared with the dry sample to ensure that the color tone of the paint is consistent with the sample.

(3) Due to the different solid content of the color paste, it is easy to produce the phenomenon of thin upper part and thicker lower part during storage. Therefore, before using the color paste, it is necessary to fully stir the color paste evenly to avoid the same formula and different batches to produce different hues.

(4) For paints that require a large amount of consistent color, especially latex paint for external use, it is best to prepare them in a large mixing tank (such as 5.0t) at one time to avoid color difference. If there is no condition to deploy it at one time, it can be deployed several times first. In the end, different batches are mixed with a part, and it can be used after stirring evenly to ensure that the color of the paint is uniform.
