What Is RGB?
The RGB color model Is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors.
RGB is a device-dependent color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual red, green, and blue levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same color across devices without some kind of color management.
Typical RGB input devices are color TV and video cameras, image scanners, and digital cameras. Typical RGB output devices are TV sets of various technologies (CRT, LCD, plasma, OLED, quantum dots, etc.), computer and mobile phone displays, video projectors, multicolor LED displays and large screens such as the Jumbotron. Color printers, on the other hand are not RGB devices, but subtractive color devices typically using the CMYK color model.
Types Of RGB?
RGB lighting
- Classic RGB: a LED strip with triple diodes (red, green and blue on one diode).
- RGB+W: A LED strip with triple diodes (red, green and blue on one diode) and a separate white diode for pure white light.
- RGBW: A LED strip with quadruple diodes (red, green, blue and white on one diode).
What Is RGB Used For?
RGB stands for Red Green Blue. It is the color scheme for digital images. RGB color mode is used if the project is to be displayed on any screen. RGB color scheme is used in electronic displays such as LCD, CRT, cameras, scanners, etc.
Advantages Of RBG:
- No transformations required to display data on the screen.
- It is considered as the base color space for various applications.
- It is a computationally practical system.
- With the help of additive property, it is used in video displays.
- It relates simply to CRT applications.
- This model is very easy to implement.
