If they used an RGO in the Renaissance/Studio, to save costs over an RGB, couldn't they just replace the RGO with an RGB in a Renaissance LE to give blue instead of orange?
An RGB and an RGO both use a common anode or cathode, with separate connections for the tri-colour LED chips in the common package, don't they?
Sure they could do that. You can have a common cathode (-) but each of the three colored LED needs it's own anode connection (+). I think there are some that have common anode vs cathode as well. But yes if they are already using 3 LED's the connections should be fine. To get a multitude of colors though you have to be able to control the brightness of each LED so that circuitry would have to be there already or added.
