RGBnäppäimistöissä

RGBnäppäimistöissä, or RGB keyboards, are computer keyboards that feature individually backlit keys capable of displaying a wide spectrum of colors. This illumination is controlled through software, allowing users to customize the lighting effects. The "RGB" refers to the additive color model of red, green, and blue, which are combined in varying intensities to produce millions of different colors.

These keyboards have become popular among gamers and computer enthusiasts for both aesthetic and functional reasons. Aesthetically, RGB lighting allows users to personalize their setup, matching the keyboard's colors to their system or personal preference. Functionally, certain lighting profiles can highlight specific keys important for gaming, such as WASD or directional keys, making them more visible in low-light conditions. Many RGB keyboards also offer dynamic lighting effects, including color cycling, pulsing, and reactive lighting that triggers based on in-game events or user input. The customization options are typically accessed through dedicated software provided by the keyboard manufacturer, enabling users to create and save their own lighting presets or choose from pre-designed themes. The technology behind the lighting relies on small LEDs, often surface-mounted devices (SMDs), placed beneath or within each keycap.
