I love my RFA, wanting to get more for sure. I have a blue and orange one that is even more bright than my bizzaro cyphaestra. What other colors do you all like?

I have 8 - and they're all over the spectrum. One is fiery red, another is orange, I have several rainbow and the last one I added is a huge yellow and green specimen.
