It is not possible to change the color of individual LEDs 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 constructed of three separate LEDs in a single casing. Intelligent technologies create unique shades by adjusting the brightness and tone to make 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.

What Makes LED Lights So Colorful?
The color an LED produces is determined by the energy levels generated within its semiconductor. 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 the go-to solution for applications that require color-changing capabilities. 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.
Red diodes use semiconductors made from aluminum gallium arsenide.
For green diodes, the material used is gallium phosphide.
Blue diodes require the use of indium gallium nitride.
Each diode can only produce the color for which it was created. When you get different current levels for each one, they shine at various brightness levels. That allows for the color wheel of choices that comes with some products.
Adjusting the luminous intensity of each diode produces a range of different colors and hues. Intelligent technologies create unique shades by adjusting the brightness and tone to make the colors customizable.
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.
Does the Color Temperature the same as the Light Color?
"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 degrees Kelvin rather than RGB.
The Kelvin scale was established by the British physician Lord Kelvin, who studied the color change of heated metals. 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 will range from 0 – 10,000K, but most LEDs will be between 2,000K and 6,500K. We had talked about the color temperature
