In general, various colors In nature and are built to have a different vision. Which form the color is called "Model Model", so it has many models that we will study the following. ags
RGB color model based on the principle of the computer.
CMYK color model based on the principle of the printer.
Model according to the CIE Lab
- Hue is the color of the reflected into our eyes. We can see the objects of colors. Each color will vary according to the length of the light waves from the object ags and is reflected back to our eyes Hue is measured by the position of the color on the color wheel (Standard Color Wheel), which is represented by the angle is 0 to 360. degrees, but generally Often referred to as the color itself. The names of colors, like red, purple, yellow.
- Saturation is the proportion ags of gray that are available in that color. By measuring the gray base color is as a percentage from 0% to 100% (no gray called "Full Saturation" is fully saturated) Saturation values are indicative of the concentration. And a color If measured by the position on the color wheel Saturation increases from the center to the edges. By the borders are clear and saturation possible.
- Brightness is the brightness and darkness of the color, which is configured as a percentage from 0% (black) to 100% (white), the higher the percentage of color to make it brighter.
RGB model was based on the combination of the spectrum of red, green, blue in different areas of concentration. By the light of the three color combination is white color combination is commonly referred ags to as "Additive" RGB light is often used to illuminate ags the screen. TV and computer screens This creates a light from the red, green and blue, the colors look brighter than they actually are.
CMYK color model has its origins in the absorption (Absorb) of ink on paper. The basic color is blue, magenta, and yellow with a mixture of 3 color above that "Subtractive Color" 3 color, but it can not be mixed pleasure.
