Smart bulbs uses RGB codes to emit different color of light. RGB codes work by mixing red, green, and blue light channels. Each of these channel can be adjusted between zero and full capacity.
By adjusting these channels, people can create 16 million different color. The light that comes from smart bulb is additive, adding colors together creates new colors, unlike paint, which is subtractive as it removes light from an environment. If a person set the channels to maximum, the smart bulbs will emit white light.
How Smart Bulbs Change Color
If the channels is set to red at maximum and the other channels to low levels, the bulb will emit a warm glow. The primary color are red at rgb(255,0,0), green at rgb(0,204,0), and blue at rgb(0,0,255). These primary colors will create the secondary colors when mixed: cyan (green and blue), magenta (red and blue), and yellow (red and green).
The color of light have a significant effect on people and can alter peoples feelings or functions. Deep ocean blue at rgb(0,119,190) can help people to focus. Forest green at rgb(34,139,34) can reduce tension in people.
Bright red and pink are used in many space for atmosphere; however, pure red can make people want to look away from the bulb if it is too brightly. If a person mixes red with some green and blue light, the color will become a coral color. Some bulbs produces white light in different ways.
The way in which a smart bulb produces white light will affect the quality of the light. Basic RGB bulbs allow people to create white light by mixing the different colored channels; however, the light can appear dingy. RGBW smart bulbs includes a white channel that allows people to produce a more naturaly light than RGB bulbs.
Color temperature is shown in Kelvins. The color temperature affects the mood in a room. Warm colors at 2700K is used in spaces where people want to feel comfortabley.
Cool colors at 5000K are used in areas where people need to be more alert. Smart bulbs allow people to create scenes for there lights to be managed throughout the day. In the sleep scene, people can set deep red lights to low brightness; red lights do not affect the melatonin in the body.
In the wake up scene, the light can transition from orange at rgb(255,69,0) to a color that is close to white. These scenes create cues for the body, which subsequently alters a persons energy levels. When buying smart bulbs, there is some specifications to consider.
People often look for smart bulbs that offer 16 million colors. However, it is also important to consider the quality of the white light. If people want the most natural tone in their space, they should seek out RGBW bulbs.
Additionally, RGB bulbs will have different protocols then RGBW bulbs, so they must ensure compatibility with their smart hub. In the case of long LED strips, people must consider the voltage drop. If they wish to have a warm incandescent color, bulbs with rgb(255,147,41) will provide the better results.
Additionally, if a color appears too harsh, it can be adjusted to 80% intensity and the opposite colors can be add to it.
