Hi, I've been reading your replies on every forum about FastLED and they've helped me a lot, so thank you. I have a question:

On lines 11-15 you declare some CRGBSet arrays. I need to do the same but they are 100 (it's contiguous groups of 2 LEDs on a 200 LED strip). Should I do this manually or is there a way of making it through a loop?

Thank you!
