Re: Color Kinetics and the RGB patent

First of all, the present state of patent affairs (at least in the US) makes me sick. There is nothing novel or unobvious to those in or out of the field about using a combination of RGB LEDs to create shades of color, as I am not a lighting expert and the idea occured to me many times before I discovered that it is patented.

Yeah, it's a shit situation, but fortunately is only having a negative impact on America's lighting industry. Patent systems in other parts of the world work properly.

I have also concluded that the color rendition by purely a combination of red, green, and blue LEDs is rotten, and so I am planning to construct lights for my own use based on a full spectrum of LED colors. Ie, red, orange, yellow, green, aqua, blue, and violet.

It's already been explored. There are lights that use supplementary colours for smoother pallets.
