How to mix colors?

1, dark red = rose red+pure black

2, purple = pure purple+rose.

3, pink rose = pure white+rose.

4, vermilion = lemon yellow+rose red

5. Chu Shihong = Rose Red+Lemon Yellow+Pure Black

6, cooked brown = lemon yellow+pure black+rose red

7, gray blue = sky blue+pure black

8, light gray blue = sky blue+pure black+pure purple

9, pink blue = pure white+sky blue

10, yellow green = lemon yellow+grass green

1 1, dark green = grass green+pure black.

12, pink purple = pure white+pure purple

13, cyan = grass green+sky blue

14, pink green = pure white+grass green

15, Garcinia cambogia = lemon yellow+rose red

16, orange = lemon yellow+rose red

17, brown = rose+pure black

18, pink lemon yellow = lemon yellow+pure white

19, khaki = lemon yellow+pure black+rose red

20, orange = red+yellow

2 1, green = yellow+blue

22, purple = blue+red

23, reddish brown+yellow+blue

24, orange = red+lemon yellow

25, grass green = lemon yellow+lake blue (more lake blue is pink green)

26. Violet = red+lake blue (adding more red is rose red)

Extended data

Although there are many kinds of colors, and there are nearly 300,000 colors that can be recognized by naked eyes, each color has three remarkable characteristics, which are also called the three major attributes (or color elements) of color: hue (also called hue), lightness (also called lightness) and chromaticity (also called saturation and chromaticity). The hue and chromaticity of any color are determined by the distribution of the three primary colors of red, yellow and blue.

Adjust brightness with black and white. Equal amounts of red and yellow mix into orange, equal amounts of yellow and blue mix into green, and equal amounts of blue and red mix into purple. Adding a certain amount of white to red, yellow and blue can make pink, light red, light blue, light sky blue, light yellow, milk yellow, egg yolk and tooth yellow have different shades.

Confirmation of color:

For any kind of "sub-color" to be blended, the standard color card or sample color of the coating film and the real color should be placed in a well-lit place or under a standard light source to identify the main color and auxiliary color in the coating film color, that is, which colors are mainly modulated by the color sample, the approximate ratio, and whether it is necessary to adjust the color brightness with black or white.

Preparation before color matching:

According to the above color confirmation, prepare all kinds of "mother color" pigments of the same kind and a certain amount, prepare all kinds of utensils for color matching, and make samples of tinplate or glass plate, and clean all utensils and keep them clean.

Sample deployment:

Open the paint bucket of each color and stir it repeatedly with the color bar. First, take a few drops of main color paint solution and drop it on the lid, tinplate or glass plate. Then, according to the order of priority, the paint of other colors is dripped in the same way as the color of the sample, and stirred while dripping until the required "sub-color" is prepared, and the sample can be prepared for many times. In the process of blending, it is necessary to confirm the dosage ratio of each color, and pay attention to whether there are any bad phenomena such as caking and floating color.

Color matching:

According to the approximate mass ratio of sample preparation, the approximate dosage of each "mother color" coating is calculated. First, 50% of the main color paint is poured into the color mixing barrel, and 50% of the calculated amount of each auxiliary color is added in turn. After repeated stirring, the coating samples were made, and then compared with the primary color samples after the solvent volatilization and floating color phenomenon were stable.

According to the degree of color difference, fine-tune the addition amount of each color in the second round, pay special attention to the addition of dark pigments, and stir less and more to prevent excessive. When it is adjusted to be close to the standard color, make another sample of the paint, and then compare it with the original color sample until the solvent volatilizes and the floating color phenomenon is stable, and it is close to the color sample.

It should be noted that if the color sample is wet film, the newly prepared paint can be dripped on the same surface for wet film comparison, which can be completely consistent. If the color sample is dry film, the transferred wet film should be lighter in color than the dry film.
