When the measured tristimulus values XYZ are converted to UCS (Uniform Color Space), they can be displayed in L*a*b* coordinates, allowing for the comparison of the magnitude of perceived color differences based on the distance between the coordinates of two colors.

I will introduce the spectrum of light (spectral distribution). The reason we perceive color is light. Therefore, to express the sensation of color more precisely and quantitatively, it is necessary to understand the properties of light corresponding to each color sensation. The properties of the emitted light vary depending on the type of light source, but they all include light in the range of approximately 380nm to 780nm. The way an object reflects that light reveals the properties of the light that enters our eyes. [Overview] ■ The reason we perceive color is light. - Color is a characteristic of the sensation obtained when light enters the eye. ■ To express the sensation of color more precisely and quantitatively, it is necessary to understand the properties of light corresponding to each color sensation. ■ The way an object reflects that light reveals the properties of the light that enters our eyes. *For more details, please refer to the PDF document or feel free to contact us.

I will introduce the process of color recognition. Color is determined by the characteristics of light emitted from a light source and the characteristics of objects that reflect or transmit that light. If we understand the relationship between the light that enters the eye and color perception, it becomes possible to express color quantitatively. This is the principle of color measurement. The measurement methods for the characteristics of various lighting sources, the characteristics of objects that reflect or transmit light, and the sensitivity characteristics of the eye to light as color perception (known as color matching functions) are all standardized as international standards (CIE/ISO). [Process of Color Recognition] ■ The differences in the spectral composition that enters the eye result in variations in visual perception. ■ The cause of this visual perception is due to the characteristics of the light that enters the eye, which is a property of light. ■ This light is determined by the reflection (or transmission) characteristics of the illuminated object, which is a property of the object. *For more details, please refer to the PDF document or feel free to contact us.

Let me introduce you to the Munsell color system. Albert H. Munsell assigned unique terms to each of the three attributes: Hue, Value, and Chroma, and established the concept of color along with these terms. By using the three elements of hue, value, and chroma as axes and arranging them in a polar coordinate system, a three-dimensional representation of color can be created. 【Features】 ■ A method of expression systematized based on human perception ■ A system that defines the elements of color (hue, value, chroma) as perceived by humans, organized to appear perceptually equidistant ■ Established as a JIS standard ■ Color representation is noted in the order of hue, value/chroma *For more details, please refer to the PDF document or feel free to contact us.

The three main elements of color (hue, brightness, saturation), known as the three attributes, combine to create colors that express various tones. Tone refers to the expression of color described by adjectives such as "shallow - deep," "bright - dark," or "strong - weak." Through the expression of tone, colors can possess rich expressions. In other words, tone represents an intuitive impression of color that combines brightness and saturation.

We live our daily lives surrounded by various colors. How can we accurately convey these colors to others? In order to enable anyone, anywhere, at any time to communicate the colors they see and feel accurately to others, it is necessary to carefully standardize each of the conditions under which colors are recognized. With the hope of being of some assistance in understanding the color measurement techniques based on this recognition process, we have created a color story. [Overview (Partial)] ■ The three major elements of form are essential for the transmission of information: - Color, Shape, Texture ■ The foundational research in color science and the practical research outcomes in color reproduction have made significant contributions to the construction of an information transmission society. *For more details, please refer to the PDF document or feel free to contact us.

The "tristimulus values XYZ" are psychophysical quantities of the CIE color space method, which recognizes color through three components as established by international standards (CIE/ISO). For example, the green color of a blackboard is represented numerically as having a red component of 5.5, a green component of 7.0, and a blue component of 7.2 compared to an ideal white. In other words, colors are expressed as three-dimensional coordinate values in XYZ. 【Method of Quantifying Color】 ■ The reflected light from an object is spectrally analyzed to measure the spectral reflectance for each wavelength, and using the calculation methods specified by the standards, it is computed into the tristimulus values XYZ for output. ■ Through colorimetric calculations, the colors represented by light at each wavelength can be expressed as three values (three-dimensional coordinates). *For more details, please refer to the PDF document or feel free to contact us.
