Lightness refers to how bright a color is. Various colored objects produce the intensity of color due to the difference in the amount of light reflected by them.
The purity of the color refers to the purity of the color, which indicates the proportion of the color components contained in the color. The larger the proportion of color components, the higher
Colors with color systems have three basic characteristics: hue, purity (also known as chroma, saturation), and brightness. It is also known as the three elements of color or the three attributes
The color of the opaque body is determined by the color of the light it reflects. The object can reflect red light, and the hail is red. Black can absorb all color light so it is black.
They appear to be distributed in the retina in a Mosaic form; Its distribution is uneven, and in the fovea area of the macula, there are almost only cones. This area has high spatial resolution (
When the visual stimulation of external objects stops, the image sensation on the retina of the eye will not disappear immediately, this visual phenomenon is called visual afterimage. The occurre
Matter itself has no color. Color is not intrinsically an inherent property of the object itself, or more boldly, that anything is colorless. The reason why we see an apple is red is because the
First of all, the medium that can see the color of the object is light, the object is subject to different light, there is a Yin and Yang back and light and dark, depth, showing a three-dimensional, c

The reason why people form the feeling of color is because of the light, but for naturally luminous objects and reflective objects, we have different principles for the formation of color feelings.
Light in physics can be defined as electromagnetic wave, people can see the light is called visible light, it is only a very narrow range of electromagnetic frequency range, wavelength range is
