First the easy answer, yes - you will need to allocate 4 channels for each separately addressed aether. The colors are red, blue, green, and white. As a seperte note, if the white channel is set to anything but zero, the other three chanels are ignored. I am also pretty sure that there will be a coop for them but that depends on demand for the unit as well as availability of the parts it requires. The rest of the questions, while thy may seem basic, are questions that only you can answer. I assume that your house is brick but that doesn't say much. What color brick, how big is the house, what shape, ect..... Perhaps if you post a picture of the house then we can give you some ideas where to start but even then, personal taste rules here.
