RGB & Color Mixing

RGB LEDs contain three separate diodes — red, green, and blue — inside a single package. By adjusting the intensity of each, the LED can produce virtually any color in the visible spectrum. Full red + full green = yellow. Full blue + full red = magenta. All three at full = an approximation of white (though not a great one).

That "approximate white" is the limitation of basic RGB. Because the white is created by mixing three colored LEDs rather than using a phosphor-coated white LED, it tends to look pale, pinkish, or slightly off. RGBW solves this by adding a dedicated white LED to the package — use RGB for colors, use the white LED for clean white light. RGBWW goes further with both a warm white and a cool white LED, giving you tunable white plus full RGB color.

RGBIC (sometimes called "addressable RGB" or "dreamcolor") is the latest evolution. Instead of the entire strip changing to one color, RGBIC divides the strip into independently controllable segments. Each segment can display a different color simultaneously, enabling rainbow effects, flowing gradients, and music-reactive patterns. Govee popularized this technology in consumer strips.
