RGBprimäärejä

RGBprimäärejä, often simply referred to as RGB primaries, are a set of three specific colors – red, green, and blue – that are used as the basis for creating a wide range of other colors in additive color systems. In an additive color model, these primary colors are mixed together in varying intensities to produce different hues. When all three RGB primaries are combined at their maximum intensity, they create white light. Conversely, the absence of all three primaries results in black.

The RGB color model is widely used in digital displays such as televisions, computer monitors, and smartphone screens. Each pixel on these devices is typically composed of three sub-pixels, one for each primary color. By controlling the brightness of each sub-pixel, the device can generate millions of different colors for the viewer. The specific shades of red, green, and blue used as primaries can vary slightly depending on the standard being followed, such as sRGB or Adobe RGB, leading to different color gamuts (the range of colors that can be displayed). The concept of RGB primaries is fundamental to understanding how color is represented and reproduced in the digital world.
