Color frequency and space Computer Shown on the image put it bluntly, but that is a combination of color-color points. However, the computer binary language of style, in fact, the difference between red or purple? The computer does not have any meaning. Then the computer is how to identify different Color What? The answer lies in each of the hardware and software associated with the visual use of a particular color space?? A kind of the way the number of display colors.

Our most common representation of color space than RGB, because our Monitor Also use this color representation. Our projection screen displays a different intensity of red, green and blue - so can display the full RGB color and shading. RGB will be a variety of colors to three the number that we call the color frequency. The definition of a color channel from 0 (black) to 255 (most saturated) three different levels of red blue and green color.

You can combine these different color channel to create a new color - as in the harmonic Pigment The same. Mixed red light and green light will appear yellow light; mixed green light and blue light will turn blue light and blue light and red light mixed purple light will appear. If you are two different amount of colors mixed together will create a frequency range of between a third new color. (For example, mixing a little red 255 there will be a small amount of orange the green).

Colors shown above can be mixed to create a pure form and bright colors. In this three-color RGB in any mix of three frequency values will be the same color from black to the evolution of the (3 color channel are to 0) White (3 color channel is 255 pm) with different Levels of non-color. When the RGB 3 therefore more similar numeric closer when no color: while increasing the same RGB values will be closer to white, the image looks gray. Arbitrary image RGB value in less than outstanding, will become more dark colors, images become more dark. The above two points - we will set all the RGB values of 0 or above 255 the following will happen then? - Will be close to the gray color, the image will become softer tone.

If you already accustomed to RGB, then you need to use some color, so long as intuition can be immediately found.

Other color space Most of the drawing tools are Package The adjustments include HSB (hue - saturation - brightness), to allow you to more easily understand the principles of color mixing. Tone refers to a 360-degree color wheel on the red coordinates to 0, the green coordinates 120, 240 blue coordinate position. Saturation and brightness is expressed as a percentage based on?? 100% saturation and brightness exhibited by a pure tone, but were added after the black and white, both of which reduce to 0.

Compared to RGB, CMYK is Print Color on paper with different amount of blue, magenta, blue and black color CMYK four-color performance in accuracy will be higher than many monitors can achieve the degree, so it is very suitable for high-quality printed works.

Color depth (Color Depth) RGB each color channel is divided into 0 to 255 different color scale, as it is available to the limit 8, and 8 bits can form a group. The amount of data used to represent color as color depth.

When we process used by the page to the picture, color depth, the following is especially important for the two projects: One is the display color depth, and the other is the storage of image files color depth. Display color depth supported by the display device in accordance with the hardware capabilities and software structure of the driver vary. Control of the operating system normally Panel The display settings allow users to set up the project required color depth. Paper color depth when the image is saved under different file formats are different.

High Color

Full color tones included far more than the human eye can distinguish the number, most operating systems offer 16-bit high color options (in the Macintosh operating system with "thousands of color, "said). In fact, high color, the display only shows 32 different degrees of red, blue, and 64 species of 32 species of green. These different levels of red, blue, green, almost impossible to visually distinguish them, but if we color depth down to 16 when a pixel, you can see the difference of color. And when the computer set-bit high color display system does not affect the time the image quality: most of the drawing program, such as Photoshop or the browser is still using 24-bit values. The color data only when the display is cut off here. This is why high-color images has been unable to common causes.
