A: People recognize colors by light, objects that reflect light, the eyes and brains of observers. Color is the feeling of light falling on the retina of the human eye. Through the triggering of light, the receiver's eyes sense a large amount of three-color light, and send electrical signals to the human brain, thereby producing a sense of color. The light that falls on the human eye is generated by sampling the reflection of light at each wavelength, and those illumination light sources flash on it. Although different wavelengths of color light will cause different color perception, in fact, all colors are composed of three basic color lights of red (R) green (G) blue (B). When the sensitivity of the three receivers at different wavelengths (one in the short wave, one in the medium wave, and one in the long wave) reaches the peak, this means that any color can be reproduced with 3 dyes, colorants, or color luminescence. , As long as their peak absorption or emission wavelengths can also be separated. It also means that colors can be matched with different color spectrum components. This phenomenon is called metamerism. Color (whether it is colored light or printing) is traditionally measured with a specific amount of RGB light matched to it. According to experience, the observer is required to match the three colors of the light with the mixed color. CIE defines the average situation of these observers as a "standard observer" to observe a specific set of "light". Then, they defined a system of measurement units and measurement procedures, so that any color can be determined according to the specified 3 standard light quantities. These are the CIE XYZ values.
Face Powder
What are the functions of face powder?
1. Make up is lasting. This is its most basic function, and it is also the most recognized and familiar function, because if you do not fix makeup, it is easy to spend makeup, and will also take off makeup. With powder powder, these problems will be solved.
2. Concealer. Loose powder also has a concealer effect, which can block the defects on the face that cannot be covered by liquid foundation or air cushion. It also has the function of hiding large pores. If there are prominent pores or blackheads, it can be solved by powder dispersion.
3. Absorb oil and brighten skin. The powder has a strong adsorption effect on oil. Whether it is applied on the face or hair, it can ensure the dryness of the skin and hair, without worrying about too bright oil. And its brightening effect on skin color is obvious.
