After searching the forums it appears this question has not yet been asked:

I am doing a custom saber using the neopixel strips from the store and am planning on hooking these up to the NBv4 module that I have. For this specific design I am using a windowed emitter/blade holder and was wondering if it was possible to light the strip in two different colors to achieve a "power light" effect. Essentially, I want the blade to light a certain color on the first four LED units on each strip, and the remainder will be an entirely different color.

Is this possible using the NBv4?
