More About RGB
RGB is a color system that enables you to represent every color in the spectrum using a unique value. That value indicates how much red, green, and blue exist in the resulting color. Usually, RGB colors are represented by hexadecimal values.
For example, the hexadecimal value for a purple hue is #8411AA. When you convert that value to RGB, it translates to 132 red, 17 green, and 170 blue.
On a screen, every pixel has an RGB value. However, that value can vary depending on the screen’s color depth, which is represented in bits. 16-bit screens support approximately 65000 colors, whereas 32-bit ones support millions of color combinations.
