LED Strip colour? Does it have to be RGBW?

Hello,

I have a question about the LED Strip: does it have to be RGBW? In the Tools and Materials section it says: "The sample code provided in this class will not work with RGB (no
white) strip, analog LED strip, or with any other kind of digital
control chip (like APA104 aka DotStar)."

How would I need to modify the code work to make it work if it was only a RBG? I found this LED strip and I thought I'd give it a try:

How would this LED strip affect the mirror?

If substituting RGB pixels, the animations involving the last white LED will not function as intended. Here's more info on RGB pixels, and the sample code that comes with the NeoPixel library should get you started:
