What is Munsell Color Stereogram? What is the Munsell color stereo of color?

Montess. Chromatography is a color marking system formulated from a psychological perspective based on the visual perception characteristics of colors. At present, the color marking system is widely used as a method for color classification and calibration.

The central axis of the Montessori color stereo is divided into 11 grades from white to black, and its hue ring.

There are mainly 10 hues: red (R), yellow (Y), green (G), blue (B), violet (P) and their intercolored yellow-red (yr), green-yellow (gy), blue-green (BG), violet-blue (PB), red-violet (RP). R+R, P+R, P+R, P+P, B+P, B+Pb, B+Pb, B+B, G+B, G+B, G+G, G+G, Y+G, Y+Gy, Y+Y, R+Y, R+Y, Y+Y, Y+Y, R+Y, R+Y.

For a finer breakdown, each hue is divided into 10 grades. Each of the five major hues and intermediate hues is given a rating of 5, and each hue is assigned four gradations.

The album is divided into 40 hues.

Any color is made with hue brightness.

Purity (i.e. H v G) is indicated, e.g. 5r 4 14 means hue is red No. 5, lightness is 4, purity is 14, this color is intermediate lightness, purity is the highest red. (In December 1978, Japan published a set of color sample cards, called the New Japanese Color System, which includes 5,000 colors, which is currently the largest number of color atlases in the world.) It is also named after the Munsell color atlas, but considering the 40 hues in the Montessori color cube, it does not meet the actual needs, especially in the R to Y and Pb ranges.

Therefore, 8 hues such as ,,, are added, a total of 48 hues, the light value is the brightness, which is divided into 10 grades, each grade is, that is, by 1, and the purity is divided into 14 grades, and the difference between each grade is 1, that is, by 1 14. ）

Red R, Yellow Y, Green G, Blue B, Purple P, Orange Yr, Yellow Green Gy, Blue-Green BG, Blue-Violet PB, Red-Violet RP.

Munsell color stereoscopic is a color representation founded by Munsell, an American educator, colorist, and artist. Its representation is based on the three elements of color. The hue is called hue, abbreviated as h, lightness is called value, abbreviated as v, purity is chroma, abbreviated as c.

The hue ring is based on the five primary colors of red R, yellow Y, green G, blue B, and purple P, and then add their intermediate hues to the vertical slag, orange yr, yellow-green gy, blue-green BG, blue-violet PB, and red-violet RP are called ten hues, and the order is clockwise. Then divide each hue into ten equal parts in detail, and each hue ** No. 5 is represented by each hue, and the total number of hues is one hundred.

Munsell uses a three-dimensional sphere-like space model to express all the three attributes of color. The three attributes of color are hue, purity, and lightness. Based on the three attributes, combined with the visual characteristics of color, it is a method to create color classification and calibration of the surface color of things.

This is the spherical space model of the Munsell system, and the intermediate axis of the diagram is distributed in the lightness levels of the non-chromatic systems such as white and black. The top is white and the bottom is black, and this is known as Munsell's luminosity value.

2-color three-dimensional**.

The hue ring around the central axis of the color system consists of 10 basic hues arranged in a clockwise direction, which contains 5 primary colors and 5 intermediate colors.

The creation of the Munsell color system is of great historical significance. The limb is lacking, because the subsequent color system is further refined on the basis of it. No matter what kind of color it is, it can be calibrated using the three coordinates of hue, lightness and purity on the three-dimensional model of the color.

Hence the birth of the method of using symbols to represent colors. Debate.

3. Slitting**.

The following figure is a longitudinal section of the Munsell color stereotype, the vertical direction represents the lightness axis, and the size of the lightness (including how many color levels) is indicated in order of 1-9.

The horizontal direction perpendicular to the central lightness axis indicates a change in purity. You can see that the left is yellow, the right is blue, and in the middle is a mixture of the two colors, which is due to the change in purity that is reflected in the constant blending.

At the same time, it also shows that the purity of the central axis of the color stereo is 0, and the outermost layer is the most saturated hue.

In 1810, Phillip Otto Runge developed a spherical 3D color model based on hue and black and white, and his theory was revolutionary at the time.

In the sixties of the 19th century, James Clerk Maxwell explored the relationship between the three primary colors and recognized that the hue produced by the addition of the three primary colors could not cover the entire gamut of perceived hues, while the hue produced by using subtractive color mixing could. He recognized that the hue and saturation of colored surfaces were less sensitive to the eye than lightness. In 1861, Maxwell made the world's first color ** based on the theory of three primary color mixtures.

Maxwell's work can be considered the foundation of modern colorimetry.

In 1905, Albert H. MunsellMunsell developed the first widely accepted color order system, known as the Munsell Color System, which provides an accurate description of color. All color assemblages described in the Munsell color space are called Munsell color solids, and Munsell color solids resemble a distorted eccentric sphere.

In 1914, Wilhelm Ostwald introduced the Ostwald colour system, which was gradually phased out by American Munsell and Sweden Natural Colour. The reason for this is that the colors selected by the Ostwald value cannot meet the needs of the dye market with high saturation in terms of arrangement.

In 1931, the International Commission on Illumination (Commission Internationale de l'Clairage International Commission on Illumination (CIE) defines a standard color system that stipulates that all excitation values should be positive and that all visible colors should be represented using two color coordinates, X and Y. The now familiar CIE chromaticity diagram is a horseshoe-shaped curve represented by an XY plane, which forms the basis for most quantitative color measurement methods.

Around 1965, physiological experiments tested Thomas Young's hypothesis that there were indeed three different types of cones in the eye.

The basic colors of hue are five colors that can form visual equal intervals: red (R), yellow vertical (y), green (g), blue (B), and violet (P), and then insert five colors of yellow-red (yr), yellow-green (gy), blue-green (BG), blue-violet (PB), and red-violet (RP) into them to form the basic hue of ten colors. Each of the basic 10 hues is divided into 10 equal parts to form 100 hue co-mold covers, which are distributed in a 360° circumference. For example, red R is divided into 1R, 2R, 3R, ......9r, 10r, then 1yr, 2yr......The color originally selected is used as the representative color of each hue, and is marked with 5, such as 5R, 5yr, 5Y, ......5rp。

The central code of the Montessori color three-dimensional axe is divided into 11 grades from white to black, and its hue ring is mainly composed of 10 hues: red (R), yellow (Y), green (G), blue (B), purple (P) and their intercolored yellow-red (yr), green-yellow (gy), blue-green (BG), violet-blue (PB), red-violet (RP). R+R, P+R, P+R, P+P, B+P, B+Pb, B+Pb, B+B, G+B, G+B, G+G, G+G, Y+G, Y+Gy, Y+Y, R+Y, R+Y, Y+Y, Y+Y, R+Y, R+Y.

For a finer breakdown, each hue is divided into 10 grades. Each of the five main hues and intermediate hues is given a grade of 5, and each hue is divided into four color scales, and the whole album is divided into 40 hues. Any color is represented by hue lightness purity (i.e., h v g), e.g. 5r 4 14 means hue is red number 5, lightness is 4, purity is 14, this color is intermediate lightness, purity is the highest red.

Munsell developed a color classification and calibration system based on the visual and pure characteristics of color chips. It uses a sphere-like model to represent the three basic properties of various surface colors: hue, brightness, and saturation.

Each part of the diorama represents a specific color and has a marking.
