I realize that this is Last Active 2 years ago, but I'm hoping to get a bit lucky! I tried using the color array in line 21 (with my own color list), but my colors do not come out correct. I'm pretty sure that this is because my LED strip is Color order GRB not RGB. If I use fill_solid ( leds, NUM_LEDS, CRGB::Red) ot works, but if I use fill_solid ( leds, NUM_LEDS, colorarry[0]) it isn't red! Any suggestions?

Thanks in advance

Hi Doug-Manning :

I need to see your sketch so that I can help you. Can you please post your sketch on either Pastbin or GitHub Gist and send me the link so that I can help you.
