Relationship Between Color and Light

It tends to think that the object is a fixed color. For example, the apple is red. In fact, the appearance of the object is generated by the way it reflects the specific light it hits. Under white light, the apple is red. Because it tends to reflect light from the red part of the spectrum and absorb light of other wavelengths. When you remove the red from the light source using a filter, the apple hardly reflects light, it looks black. The fact that the color composition of the light can be changed means that there may be an offset in the appearance of the color of the illuminated object. Within the limits, the brain complements these changes in color appearance, and we see what they expect to appear. However, these changes still affect how people respond to things and the environment.

There are light of various colors, and they look white. Direct sunlight at noon is a perfectly balanced light source - it includes nearly equal numbers of all colors. However, the color of sunlight changes. The appearance of the color of the object changes greatly in the morning and in the shade. Electrical light sources may also exhibit changes in color tone. Incandescent lights tend to generate more red and yellow light than green and blue, and they look like "warm" colors. Because of the way incandescent lamps are manufactured, it is rare to manipulate their color characteristics. This state-of-the-art technology uses fluorescent lights and high-intensity discharge illumination to control the color composition of specific light sources

In general, white light (which is composed of the same number of all colors) shows the color more natural and vivid. However, some parts of the spectrum are more important for the color composition of the light than the other parts. The primary colors of light, red, blue and green, can be combined with almost any other color. This means that a balanced amount of light sources of red, blue and green light can provide a superior color appearance even if the light source lacks other colors in the spectrum.

Combination of light and color in interior design: The basic concept and color of light and shadow explain not only interior design and interior design but also the relationship between lighting and color, light and shadow in interior design The combination of interior colors will be displayed from the interior. Application method for enriching and exploring the combination of light and color art design in indoor environment

Background: The relationship between light and plant growth can be proved by exposing the leaves to light of various colors. Light provides energy for leaf photosynthesis and food production. However, the most common spectrum of blades is limited to three different colors, red, blue and yellow. For example, green is a color that most leaves absorb and does not use but reflects, leaves look green. Procedure: Plant four soybean plants of the same size in a tank containing wet soil, spread the recommended amount of fertilizer Place a color filter tent on each plant The filter should be transparent Please use blue Please put the color, yellow, red film aquarium of other filter in direct sunlight, place the water in the same place every day during the experiment, measure each plant every day, Please record it in the note, please measure from the bottom of the aquarium, not the surface of potted soil.

The relationship between color and temperature is very convenient, and various processes and equipment make use of the relationship between temperature and color. One example is photographic film and lighting equipment. The color film contains photosensitive chemicals that record hit light. Various chemical substances are sensitive to light of various colors. Mixing of these chemicals on the film affects the sensitivity of the film over the visible spectrum. What you want is a "balanced" movie, ie, it is sensitive to the same proportion of different colors present. However, these ratios vary depending on the light source. Solar balance film is different from flash film balance. The incandescent lamp is still different. Film makers (Kodak, Fuji etc.) designate the balance of the film by specifying the temperature of the light. For example, the temperature of the sun is 5500 K.
