What is the RGB color mode?

RGB color mode is a screen display mode; on the monitor, the RGB color mode produces colors by hitting the red, green, and blue light-emitting electrodes of the screen with an electron gun. Computers can generally display 32 There are about one million colors. The RGB color mode is a color standardization mode that uses the three basic colors of red, blue, and green to produce other colors by superimposing and mixing them in different ways. These three colors are also the three primary colors that produce other colors, and can form all seen color.

What kind of mode is RGB color mode?

RGB color mode is a screen display mode.

RGB is the color mode of color light. Also called additive color mode.

RGB color mode is a color standardization mode that uses the three basic colors of red, blue and green to produce other colors by superimposing and mixing them in different ways. These three colors are also the three primary colors that produce other colors. It can form all the colors we have seen, and the various color systems produced according to the different proportions of each are often called RGB.

It is a processing standard for our colors. R is the English abbreviation of red, B is the English abbreviation of green, then B is of course blue The English abbreviation of color, In addition to RGB mode, there are actually many modes we use, but RGB is our most common color mode, there are also CMYK mode, Lab mode, Hab mode, common ones That's RGB and CMYK.

There are also several uncommon ones such asBitmap mode, grayscale mode, duotone mode, indexed color mode, multi-channel color modeWe generally don’t use these types , this is a mode that is only used for special operations. What we generally come into contact with is the RGB mode. Although many people are exposed to various colors every day, they may not understand this color mode very well.

Because they have not had an in-depth understanding of this knowledge. Nowadays, people have used computers, TVs, or mobile phones. The various colors on the computer screen and TV screen are composed of RGB. They are composed of different proportions. A group of red, blue and green are the points that make up these pixels. Many people may compare whose mobile phone pixels are better every day.

But they may not know very well what good pixels mean. Good pixels means that you have more pixels. Each color pattern is composed of many dots. Buying these dots is a set of RGB,The more points, the higher the pixels, the brighter the color, and the clearer the image. The brightness on the computer refers to the number of RGB, and they are all integers. RGB generally has 256 brightness.

Starting from 0 to 255, this is one brightness, three colors and three 256 brightness, The 0 among them is not the same as in our lives. can be ignored, which is also a brightness. Each primary color has 256 brightnesses, so the number of their combined colors is 256 cubed, which is about 16.78 million colors, so we also generally call it tens of millions of colors .

Sometimes it is also called 24-bit color, which refers to 2 to the 24th power. The more they exist, the more realistic the colors of the world we see will be. , such as The composition of white on the computer is 255.255.255, and the corresponding black is 0.0.0This is the color numerical code on the computer.

In RGB mode, other colors can be produced by superimposing red, green, and blue, so this mode is also called additive color mode.

Application of RGB color mode

Most monitors adopt the RGB color standard. On the monitor, the red color is shot on the screen through an electron gun. , green, and blue light-emitting electrodes are used to produce colors. Computers can generally display 32-bit colors, and there are more than one million colors.

All monitors, projection equipment, televisions, and many other devices rely on this additive color mode.

In terms of editing images, RGB color mode is also the best color mode because it can provide a full-screen 24-bit color range, that is, true color display.

However, it is not optimal to use the RGB mode for printing, because some of the colors provided by the RGB mode are beyond the printing range, so when printing a true color image , it will inevitably lose part of the brightness, and the brighter colors will definitely be distorted.

This is mainly because the CMYK mode is used for printing, and the colors defined by the CMYK mode are much less than those defined by the RGB mode. Therefore, when printing, the system automatically converts the RGB mode to the CMYK mode, which is inevitable. Part of the color is lost and distortion occurs after printing.

In the LED field, three-in-one pixel matrix full-color technology is used, that is, RGB three-color chips form full-color pixels in a light-emitting unit. As this technology continues to mature, LED display technology will bring people a richer and more realistic color experience.
