I personally like red as my AV switch color. I got blue on my first sound saber... got red on my second.... and just couldnt help myself and got red again on my third.... For me, I like how the red looks with any color blade.
My emerald saber has a red AV.... I got it in series with ch.1... I love this set up, however.... I rarely, if ever, use ch.4(white)... If i were to get an rgbw saber again i would just put the Av by itself on ch.4.
How do you brighten colors without white or can you?
