RGB stands for Red, Green, and Blue, and these are the primary colors of light.
RGB color system is an additive color system, which means the more you add, the more you get closer to white. Whereas in the RYB color system, a subtractive color system means the more you add, the more you get closer to white.
Red, Green, and Blue are the primary colors of light, and they range from 0 to 255. The value shows the intensity of each color. All the other colors are formed by combining these three-color values (0 to 255).
So if Red = 255, Green = 255, and Blue = 255, then it would be the white color.
Some best photo editing and graphic designing software like Photoshop, Adobe illustrator, fireworks, etc., represent or show the color system in RGB format.
What is HEX color?
The HEX color system is linked with the RGB color system. In the HEX color system, the color is represented with Hexadecimal string (words, numbers, or combination of both), about its mixing in Red, Green, and Blue.
The color code starts with the hashtag (#) sign in the HEX color system, followed by the six letters. These six letters are the actual representation of Red, Green, and Blue color. Among these six letters, the first two letters represent red, the second two letters represent green, and the third two letters represent green.
HEX Color Codes vs. RGB Color Values
Even though the HEX color system is linked with the RGB color system, both have different uses.
The HEX color codes are safe for web browsers, meaning whatever browser you will use will provide you with the same color results. That is why it is used in website designing, logo making, etc. Simultaneously, the RGB color system is based on light colors and is used in monitors, television screens, cameras, and digital cameras.
