3 years ago I think that this may be a hardware issue rather than a software one. It looks like that first LED isn't getting the data signals properly because it is both showing the wrong color and it's on full brightness rather than the brightness level you've specified in your code.
Do you happen to have another LED hanging around? If so, can you try replacing that one? Another thing you may want to try is placing a single LED between the module and that first LED. You don't have a logic level shifter there which usually will work fine, but using a sacrificial LED at the beginning can also help in that situation.
I'm having issues with my first LED not showing the correct color. It always shows LIFR basically a purple color. Any ideas? I've attached my code and some pictures. any help would be great!
