It is not possible to change the color of a single LED diode in the strictest sense. Modern RGB LED technology combines red, green, and blue diodes in a single unit to produce a wide range of hues. These color-changing LED bulbs are typically made of three separate LEDs in a single casing. Intelligent technologies create unique shades by varying brightness and tone, making the colors customizable.
Advanced LED technology available today can generate up to 16 million color combinations, making them ideal for commercial environments that require dynamic, customizable lighting, such as retail displays, hospitality venues, and architectural features.

The color of LED light depends on the semiconductor materials and energy levels used in the diodes. Each material used in the semiconductor influences how much energy is released—and in turn, what color the LED emits. That’s why a standard single-color LED bulb emits just one specific hue.
RGB LED bulbs are commonly used in applications requiring color-changing lighting. These bulbs house three separate diodes—red, green, and blue—within a single unit. By adjusting the intensity of each diode, the bulb can produce millions of color combinations.
Each diode can only produce the color for which it was created. When each diode receives different current levels, they shine at varying brightness. This allows for the color wheel included with some products.
Adjusting the luminous intensity of each diode produces a range of different colors and hues.
For example, if you put 100% of the current into the red diode, that's the color you'd see from the LED light. The same is true for the blue and green options. Should the red diode receive 100% and the green 50%, you'd get a shade closer to orange to use for your home. When all three diodes are fully open, white light is produced.
"Light color" refers to the color of light emitted by the diodes of an LED light. And color temperature refers to the shade of white light emitted. White light can produce a warmer or cooler visual effect, which is measured in Kelvin rather than RGB values.
The Kelvin scale, named after Lord Kelvin, measures the shade of white light. He found that as the temperature of the black material increased, its color changed from red to yellow and finally blue.
Unlike air temperature, which is measured in degrees Celsius or Fahrenheit, warm color temperatures are lower in Kelvin, while cool colors are higher in Kelvin. The Kelvin scale ranges from 0–10,000K, but most LEDs are between 2,000K and 6,500K.
