One of the amazing factors about LED is that they are able to produce a variety of colors which are bright and clear. Unlike conventional lighting devices, LED is able to mix and combine various shades of colors as they have a rich source of RGB (Red, Green and Blue) elements.
Naturally, the more combinations are available, the more colors and shades will be available. This means that using more RGB bulbs will allow the particular LED devices to produce more colors and surely more variations of a specific hue which means that the device can be used in larger screens and display panels.
