Color is determined by wavelength. Talking about light, there are 7 colors in the eye. Newton discovered that the eye has 7 colors. 7 colors (VIBGYOR) wavelength values 400-750 nm. Types of Colors.
Types of Colors
What Are The Primary Colors of Light
Red, blue and green is called primary colors.
What are Secondary Colors?
Secondary colors are formed when two primary colors are mixed equally. Mixing red and blue produces dark red. Mixing blue and green produces peacock blue. Yellow color is formed when green color and red color are mixed.
What are Complementary Colors
The color resulting from the combination of two primary colors becomes the complementary color of the third primary color. Red primary color produces peacock blue, green primary color produces dark red color, and blue primary color produces a yellow color.
White color:
- White color is obtained when three primary colors are mixed equally.
All three secondary combine equally to form white color.
A primary color and its opposite secondary color together give the color white. White is formed with red and dark blue. White color is formed with green color and dark red color. White is formed with blue and yellow.
Colors in Color TV: In color TV the primary colors are red, green, and blue.
Color printers include dark blue, dark red, yellow, and black. This is referred to as CMYK. When white light falls on objects, only those colors are reflected and the remaining colors are absorbed.
Visible light when the light of different colors falls on objects
A colored object appears to be the same color when viewed under the same color or white light. It looks black when seen with other colored light. A red object appears red in red or white light. It looks black when seen in any other color light. If the red light is shone on a yellow object it will appear black.
What is the scattering of light?
The process of light scattering in all directions on air, dust, dust, and moisture particles is called light testing. At sunrise and sunset, the light from the sun has to travel a long distance through the earth’s atmosphere to reach our eyes. All colors except red light are overexposed and disappear before they reach our light. Red light is less sensitive than it reaches our eye. As a result, the sun appears red at sunrise and sunset.
Sunlight travels less distance in the atmosphere at midday than in the morning and evening. So all the colors reach our eye because the light is not tested too much. Hence the midday sun appears white.
