You see this all the time with professional lighting fixtures as well!

For example, the ETC Source4 LED Lustr X8 has: Deep Red, Red, Amber, Lime, Green, Cyan, Blue, Indigo[0]

RGB LEDs are pretty crappy at rendering colours as they miss quite a lot of the colour spectrum, so the solution is just add more to fill in the gaps!
